Battery Life - Desire General

Hi
Had my phone a little over 24 hours and I may have a very poor battery
I have a LIVE screen on the one with the water and the leaves plus, I haven't made or received any calls but I have used it a little for internet and a few text messages
The green bar was on full about 5 hours ago and if I had to guess how long my use has been I would say 30 mins in total of the 5 hours, now my battery is indicating less than half full
Imagine if I was out all day making and receiving calls?
Does this sound normal?

This is normal for the first week or two , the battery is adjusting itself to your needs

It's absolutely normal and you'll really notice a difference in about ten days, a couple of weeks the most.
That said, live wallpapers do use more battery. I much prefer a static dark one

adding to that make sure your phones nicely drained before recharging to ensure you get a nice full charge for next time... i took my desire's battery at least 5 days to start having a long term charge

bettery
same here took a week also what really helped me is having advanced task killer and setting it to kill unwanted apps after i lock the screen

i dont think you should use task killer, the apps will end them selves, i used task killer and got alot of force close after and errors etc
however force stopping unwanted applications is also good.

Android system 30%
cell standby 25%
phone idle 17%
android OS 15%
Display 11%
Internet 2%
5 H 55M 55S unplugged, hahaha no joke its all 5's
and now my battery is almost dead surely this cant be right
has anyone ever been given a replacement battery for their phone or do they ask for the phone to be returned if this is infact a fault

Battery sucks, phone is power hungry. Get used to it
I've had 2 desires since a week after it was released, i can count on one hand how many times I've got through a day without plugging my phone in.

I get about 2 days on my phone if I don't mess around with it a lot or get many calls. I normally plug it on overnight. Every night.
Nowadays that seems normal for a smartphone. Personally I think the battery life is slightly better than the iPhone 3GS.
Angry Birds means it lasts about 4-5 hours...

It's all down to how your using your phone. If you have a live wallpaper and many widgets and apps that run in the background like running in the notification bar, then yes, your phone will die pretty fast. Also it depends on how much CPU your burning. When I first got my Desire, I was like WTF. This is useless battery life and was starting to play hell. Now it's fine. I can leave it for 2 days easily if I just text or flick through settings. It just depends on what your running.
BTW, no one should have a task killer. It defeats the purpose of Android. You can get a lot of force closes and other things. Just leave them alone and let the OS handle the apps. Android does end the process if it's idle, eventually, but it's not using anything really other than a bit of memory just to keep it going a little.

As GoogleJelly pointed out, it really does depend on what you do with your phone and what's apps/processes are running on it while the device is using battery. Even I found the battery life pretty poor at the beginning...I found it quite annoying having to charge this thing nearly every day.
After some light tweaking, I managed to get the battery life to go over 3 days and I now have no reason to complain about my phone Mind you, I'm not a heavy user....As for background apps, I think i've got about 5/6 apps running at a time...
EDIT: I've attached a screenshot of my battery meter.....

What app are you using to view your battey history?

I also tested task killer when I got my phone. I thought it was fixing battery life, but after bedding the phone in a bit I took it off to see how much difference it would make and I didnt notice any difference at all...

I configured Quick Battery app to go to battery history from my phone settings every time I tap on it. You can view your battery history through:
Settings > About phone > Battery use.
If you want the graph, just tap on the top layer which shows the length of time you've been on battery.
EDIT: This works for Gingerbread based ROMs (it's the standard feature lol)...can't remember this being on Froyo.

This is irrelevant with Li-ion as this is a myth from the ages of NiMh batteries. Your battery will not get ruined if you don't discharge it completely before first charging.

Ah right, cheers for that. Didn't know it was all built in

One of the main reasons why new smartphone owners experience fast battery drain lies in the simple fact that they fill up seven homescreens with widgets that sync over mobile internet every hour or even more often, which really kills the poor juice like a massive gas leak.
After about half a year of use I've reached a stage where I use just 2 screens on my Desire (CM 6.1.1), of which page no2 is a full 4x5 agenda and Page one has just one actively updated widget (home weather).
Combined with restricting network usage of random apps by means of DroidWall and underclocking the processor at certain parameters (eg. battery <50%) the phone lives for 2 days pretty easily, with moderate browsing, music etc included.
But TBH I've really decided that the battery usage is absolutely random because some days it just drains like there's no tomorrow with no apparent reason that I've been able to identify. Carry a spare microUSB wire tbh :/

I read so much myths in this thread concerning Li-Ion batteries.
First of all Li-Ion batteries do have instantly the capacity they are intended for. Even 5 charges won't change that. The only thing which can change over time and charge-cycles is your phone recognizing a new voltage level as "full" (read more: "calibrating htc desire battery") or you playing less with the phone or having power-consuming apps uninstalled.
Also a full first charge is not necessary. This "requirement" are from past days with NiCd or NiMH battery-types.

The calibration during the initial week or so of using the phone arises from phone-side calibration, not the battery itself, which is why deleting battery stats from recovery can at times resolve battery issues :V
Phone didn't last half a day after flashing CM 6.1.1; after a couple of days I charged it to 100%, deleted the stats and voila, it's about as perfect as a terrible smartphone battery can get.

Desire battery life

Any pointers for increasing battery life? I've disabled live wallpapers, picked a dark background, set friendfeed etc to update every 4 hours, and it's still not great. Phone is new, should I expect battery life to improve as battery gets used a bit?
Are task killers worth using? Seems to be some debate that they might actually cause more problems than they solve.
I've gone through forum and found lots of generic advice but would appreciate any ideas people have tried on the Desire.
Do I *really* need to wturn off wifi when I'm not using it? Isn't the phone smart enough to not use it when a known-network isn't present?
Cheers
From my experience i would advise against having a task killer running.
I used to have one running on my N1 and thought, "Great, i can free up memory". But you really don't need to do that with Android.
Having disabled it from running, I get to teh end of the day and I have between 75 and 85 battery, after having done a fair few phone calls, some net fun and data access.
I still have a task killer but I use it infrequently and dont have it running - i let it "kill" itself after running it.
I found they take up a good deal of battery life. But that's just my opinion.

Of course!
The classic task killers kill services that are sleeping and do no eat battery.
A few minuts later, on some receivers ( connexion to internet, message or SMS received) these services will restart, and that's where they are eating battery.
If you hadn't killed them, they would have done that without eating battery.
Waking up and then going to sleep is really less battery-eater than restarting the whole service.
So, please forget about all these task killers or do that in a smart way. Only kill your game or the latest app you used!
Battery life will improve over the first weeks use. Needs a few charge cycles to achieve full capacity.
Although the battery life might not be as good as some other "imore ipopular" handsets at least you can buy a second reasonably cheap battery if you know you will be a couple of days away from a possible charge (camping etc).

You serious? I am guessing you're referring to the iPhone, the smartphone that is on charge more times than its off charge?
My Desire hands down beats an iPhone for battery life by almost 100% - only ever got 1 day of an iPhone at best - Desire is approaching nearly 2 days full usage, I am no lite user either.
For battery life the Desire is one, if not the best out there at the moment.
thank christ for that, i presume it improves after a couple of charges. mine was new on friday and the battery's pretty uninspiring so far...

My Desire has been up for 21.5 hours and has 3 bars left (according to the settings battery meter) but I've been driving around most of the day with spotify on listening to music, quite a bit of surfing, emailing, calls and a few texts.
I reckon it's probably got another 5+ hours to go yet.
My phone is quite new and battery life is starting to improve daily now.
Hmm... struggle to get more than 5 or 6 hours out if mine under relatively light usage, maybe 20 mins calls and 3 or 4 texts, if I use browser it flatten quicker still, the battery use status usually says Android OS itself has used most battery.
Hoping it will improve, at moment it is poor compared to my TD2 with a smaller battery
P.
had mine about 6 days and my battery is ver poor at the moment. however i remember thinking that about the G1 at first and it got better.
still was luck to get a full day from it. however i went to europe the other week (from uk) so turned all roaming data and syncing off and it lasted 4 days.
fingures crossed battery life increases on the desire, gor a car charger on orded fron fleabay so i should survive
i loved my G1, and found it hard to upgrade, first time thats ever happend, but wow this desire is differnt class, my wife has the iphone and is green and my 16 year old son is gutted he got the hero only 6 months ago.
Re: desire battery life
I've been running my desire for nearly two weeks now.
As usual WiFi & gps are the main culprits.
On average, I have exchange & GMAIL push on 3G all day with a bit of Facebook, sms & several min long calls without going past the three quarter mark by 5:30pm . However as soon as I switch on WiFi at home for browsing, reading news feeds, market etc, bang goes my battery!
Turn off 3G and sync and use it as a phone.......great battery life!

Yea not sure how you guys get good battery out of it. I have everything off, dark background, no synching due to having mobile network off (only thing setup to sync is email every 2 hours). I take a few phone calls maybe 30-40mins, do about 15 mins of surfing, 30 mins of music through headphones at low volume, and a game for 30 mins. That pretty much concludes my battery life for the day (is usually at around 20% left by the time I get home).
I find if I browse the market and download/install apps, my battery will go down very quickly.
Got my desire for a week now and it lasts me 2 days woth some movies, wifi and messaging. if i go even lighter, only messaging and calls it lasted me almost 4 days. it has great battery in my opinion, better than my old hd2 and even better then my old old diamond
Over in General we found an issue with the calendar app keeping the phone from going into sleep mode - That could be a cause for poor battery life.
The thread is here (remove spaces please):

My Desire have no problem on battery so far tho, 1½ day with normal use is no problem. litle use i can use it around 2 days, but with alot off things running i would say for sure it works over a full working day.
Mine has been running for 20 hours now, I have mainly been calling, texting, surfing the net (mainly facebook), and playing a game a couple of times.
I'm not really sure whether this is good or not, I would rather it lasted longer than this, as it is due for a charge within the next few hours, and this is a bit of an awkward time to need to charge it. If I wasn't off work today I'd have a dead phone before I got home.
I don't like to charge mine before it tells me too, I like to think it'll improve the battery life over time? Is this right?
those batteries are not affected by memory effect. charging everytime you can is better than drain battery to 0%
HTC have said there is a software issue with battery levels hench the charging issues. Fix in the future they suggested.
Weather this effects the actual life of battery not sure.
I have just come from the HD2
At the beginning, everyone agreed that the battery life was god awful, and a month or so in everyone reported that the battery life was outstanding!
I can confirm this, to start with it wouldnt last me a day, by the end of it i could leave 3g and wifi on all day with everything running in the background and get a good 2 full days out of it!
I just received the desire yesterday, i gave it a full overnight charge and i must report that for the first charge the battery life looks very promising
I have used the phone VERY heavily even for me with about 100 texts, an hour talking, an hour on the internet and syncing every 15 mins or so and i have 2 bars of battery left, and i said, the battery is only going to get better!
You should look at power management tips for the HD2 as most of them apply, for example disabling 'automatic backlght' and setting it yourself because that alone can add about 30% to your battery life.
currently at 2 days 15 hours with 6/10 battery bars left.
i have gps/wifi/internet disabled and turn them on with the settings widgets when i want to use them. screen brightness at about 20%
the battery is great IMO
Guys could u please tell if I should when receiving my phone charge it directly (full charge) or it's better to empty it completely and then charge it ?
Thanx

[Q] Desire HD battery life question before I buy

Hi,
I'm planning on buying a Desire HD, but just curious about battery life before I lay down a grand on it.
At the moment I have an HTC Hero, when they were in their heyday many people complained about the short life on them. I can get 2 days out of mine, with syncing over wifi enabled the whole time. I put the complaints down to people with background apps sucking CPU or too much twitter/facebook/whatever crap syncing as well.
Now most of the reports of poor Desire HD battery I life are from people on their first charge (who clearly don't understand the characteristics of Li-ion batteries), people who expect to be able to thrash the phone all day with the screen on without it dying and generally people who just don't sound like they know what they're talking about.
I know there are two bugs which peg the CPU at 100%, the one fixed by having debugging on and the calendar bug, which sounds like it can be fixed by clearing calendar data or leaving syncing off. I think these were affecting some of the people who were complaining about the short battery life.
So my question for Desire HD owners is, can you last at least 6 am till 10 pm with a bit of use (something like 10 min browsing, 20 min IM, email syncing all day, 1 hr music, 20 min calls) without it dying? Currently my Hero does this fine and a full day without a charge is a requirement for me.
Thanks.
Yes, if you set it up correctly. From your post it sounds like you know what your doing when setting it up.
Before i tried the battery calibration i was getting from 8am to 9pm with moderate usage. TBH i was put off by using it as I thought it would just die on me too soon.
After the calibration (search forum for it) i got from 8am to 4pm the following day where the 15% warning hit. So do the calibration and you'll be as happy as i now am with it. I never got my iPhone 4 to last that long!
Thanks for the info guys, exactly what I wanted to hear!
I haven't taken any precautions to save battery life and I am getting 25-26 hours on a full charge...and now having had the phone for 2-3 weeks it seems to be getting even better!! I've been getting 36 hours out of a full charge these past 3 days.
I do not turn wifi off. I have screen brightness on auto. Syncing lots of stuff hourly (even weather!). I use 3g when I go out but this is about 2-3 hours tops on week days cause I have wifi everywhere i go. battery life has never been an issue for me and I use my phone frequently...play games for 20-30 mins. watch videos via. skynews, listen to some music etc. etc.
As for the bugs...I do not have usb debugging turned on and I have never had the /INIT problem...perhaps it was fixed in the last update? and the calender bug...never had that problem either and I use my calander with google calander, facebook, holidays and person agenda.
I think you'll easily last a day with the usage you mention. As a rule, I think you normally get up to 4 hours display on usage off a charge (browsing, messaging, watching vids etc).
I'm travelling from Ireland to NZ on Monday, which will equate to 36 hours travelling with probably no access to a charge, and lots of time spent sitting around using my dhd. There's no way the phone will last right through, so have bought a 5000mAh USB battery pack for £20.

I'm currently at 22 hours and still at 42%.
I get 2 to 4 hours depending on useage from full charge. 8 - 9 hours if left on standby and not used for anything.

Well...I think I have had similar results....
flash one of the custom roms, with one of the OCUV kernels and setting max. speed to one of the UV speeds (mine is set to 1.1 Ghz which is UV 50mV), also setup useful profiles in Setcpu (I have set screen-off to use max 384 mhz - which does cause a 1-3 sec lag when screen is on again) and <20% battery etc...
of course, if you play heavily with your dhd you will not get these results, so you can put wifi on with this , but need to think of what you want to do, because using your DHD for 2 days, does require limited screen usage (imho, this uses a lot of battery)

8-9 hours on standby???????????
even 2-4 hours whilst using it is terrible!!! When I got my HD and unpacked it I didn't put it down after a full charge and I got 8 and a half hours with non-stop heavy use.
I think you have a faulty battery!!

I too moved from a Hero to a DHD and I can say that with similar usage, the DHD loses to the Hero by a decent margin..maybe u might get a couple of hours less of usage compared to the Hero but the difference isn't very drastic
Moreover on the Hero I'm using CM6.1 Froyo overclocked and the DHD is on Sense, so logically speaking the Hero should get slightly better battery life on CM6.1 compared to Sense. I'm sure after rooting and flashing CM6.1 and undervolting/underclock the DHD, i'd get better battery life because the DHD is like much much faster than the Hero, so I'm sure even if i underclock it, it'll still be super fast.

The battery is 'fine' i'm using current widget to track and its performing to around 1100 mah which is not too far below spec. The problem is the current draw. In use i'm drawing 500 to 800 mA and in standby around 80 to 300 mA. These figures are consistent with the battery life I'm seeing and the battery working close to spec (1230mAh i think?)
There are lots of bundled apps like Maps running all the time in standby drawing current and I haven't yet figured out how to stop them. Stopping them with task manager just sees them restart with even bigger current draw.

Something is definitely wrong (as I'm sure you're aware) with only 9 hours on standby.
Out of interest, remove ALL widgets and see what difference it makes. Also, give us an example of what processes are running?
I would get rid of all task killers and also anything monitoring your system. Those themselves can draw more than you think.

wow well I'm no battery expert but it really sounds like something is not right there. I don't have any battery drain from apps in standby and I do use maps.
I got 1 day and 16 hours from a full charge today (just put it back on charge now).
Thats with wifi on for 31 hours (always on, doesnt sleep when the screen locks), 1 hour and 24 mins of talk time and the screen on for 4 hours and 5 mins.

thats definitely wrong somehow.. should never drain that much, perhaps it is because you let currentwidget drain it all the time
(na dont know why it is like that but it definitely is way too high)
official firmware, medium screen brightness, default sync widgets
heavy use: 12-15 hours
light use: 24 to 36 hours
this is how its been for me ever since the battery calibrated, needs around a week or use the battery calibration trick
I too have just moved from a Hero (running VillainRom 12) to the DHD (stock Sense over FroYo) and even though I have only had it a week, the battery easily lasts a whole day with the moderate use you describe. Unless I get stuck into a session of " Angry Birds ", which seems to kill the battery pretty fast. But ABs had the same affect on my Hero. Constant screen time on that beautiful 4.3" display sucks the battery. I find the same thing when using the DHD as an in-car gps. The warmth of the back of the case is testament to how much energy has been expended. So I connect to the car charger now. I have also bought a portable backup battery (plugs into the microUSB) just in case.
I don't regret spending NZD1000 on the DHD. My son is looking forward to inheriting the Hero.
Well I charged it up overnight when I got it, my first full day was today and I got 7 am till 8:30 pm using it almost constantly (quiet day at work). I don't know how people can run them flat a day with normal use. And I know it'll improve a lot after a few charge cycles.
It doesn't look like it's going to be much worse than my Hero.
Thanks for all the advice. I uninstalled all widgets and it improved a little. But still things like maps/maps sync were constantly burning juice and no way of stopping them running.
I installed Launcher Pro and can report that my battery life has approximately doubled. Typically i was getting 4 - 6 hrs use and sometimes only 2 (light use). Now getting between 8 and 12 hours of fairly heavy use. Its still not up to some of the figures others are reporting but Launcher Pro has helped a lot as all those constantly running apps that were draining my battery just dont start themselves up any more!

HD2 WP7 battery

ok so I used my phone for about 3 hours last night tweaking things and playing with stuff and didn't charge it overnight and used it a bunch today and the battery indicator looked like it was at about 70%. probably not accurate, but the fact that it's even still on amazes me because it's probably got 8 hours of playing with it and 6 hours of standby and still going strong.
I think a full drain then a full charge might reset the battery indicator for accuracy, I wish we had like a "current widget" for WP7 to see the ma drain.
how you guys doing on HD2 WP7 battery drain? Mine seems to be even better than WM6.5
I have the exact opposite experience as you. My HD2[7]'s battery life is crap. It was fully charged last night and I had left it in my drawer with the Wi-fi off. After coming from work a half hour ago, I saw that the battery was almost drained.
Also, shouldn't the battery icon show the plug when the phone is being charged? My phone is on and booted into WP7, the red light is showing but the battery icon shows no animation or the plug. EDIT: WTF IT FROZE ON ME, I had to remove the battery!
Finally, what's with the random reboots? I've seen 2 already.

I think its something related to the SD cards you are using.
If the Sd card you are using is not compatible with WP7 then you will get random reboots.
And the main thing here is that there is no specific way to know which SD card will work and which wont work with WP7
By the way my battery is somewhat draining faster than the Android I was using on my HD2

What I meant to say was, we don't know which SD card will work with WP7 on HD2.
I wasn't talking about the official WP7
Well the stock 16gig TMOUS card works just fine.
my battery seems to be fine, i use my scale based on my school schedual. with android from 7 am to 4 pm around 50 to 40 percent.
today running wp7 i unplugged it around 8is and about 6 is it had very little black on the battery icon. im going ot charge it up fully, then kill it, to see if that helps reset the battery stats
Well when i first flashed WP7 my battery was over lasting.. After i manually rebooted because i just felt like doing so, my battery has started to drain a little bit to fast.
Are there any marketplace apps that can monitor this stuff yet?
Update: Last night, after making sure that my phone was fully charged, I turned off the wifi and removed the SIM card and didn't touch the phone again until a half hour ago (about 12 hours standby time in total). The indicator is showing about 50% battery life remaining. This SUCKS, and any helpful comments about this will be appreciated.
just considering its not supposed to be on the phone...
also what theme are you using
and since microsd polling it may have a lot of impact on standard battery life...
plus, let's be real, it is an htc...they're not battery efficient

plus, let's be real, it is an htc...they're not battery efficient

Here are my settings: Dark background theme, purple (hate the color normally, but somehow manages to look nice on the HD2), 30 seconds lockscreen timeout, Wifi off, Location off.
I tried removing the MicroSD, but the phone then becomes unusable with frequent freezes and reboots. I'd love to check if the card is affecting battery life if the damn phone would let me to.

I have the exact opposite experience as you. My HD2[7]'s battery life is crap. It was fully charged last night and I had left it in my drawer with the Wi-fi off. After coming from work a half hour ago, I saw that the battery was almost drained.
Also, shouldn't the battery icon show the plug when the phone is being charged? My phone is on and booted into WP7, the red light is showing but the battery icon shows no animation or the plug. EDIT: WTF IT FROZE ON ME, I had to remove the battery!
Finally, what's with the random reboots? I've seen 2 already.

HTC puts bad batteries in their 4.3" phones. They've been using 1230 mAh batteries forever (over a year). Blackberry curves come with 1150 mAh batteries so you can see what that size is somewhat optimized for: feature phones and smartphones with small non-touch screens.
Most smartphones with a 4"+ screen running Android or WP7 have 1400+ mAh batteries (the i4 and Droid X also have 1400, Galaxy S and Incredible have 1500). That's why the battery life is bad.
And it's also the reason why I've never really given the phone much consideration - the battery and the TFT LCD screen they used on it.
That being said, the battery life depends on you usage. When I used my HD2 as myprimary device the battery life was terrible. Once I got my Vibrant and used it only as a PMP, the battery life was terrific because it didn't have a SIM Card and I only used it on WiFi and to play Music and Videos.
But people who use Curve 3Gs as their primary devices and are constantly BBMing and/or SMSing people in addition to calls report days-worth of uptime (emphasis on the plural).
My battery life is on par with what it was on android (about 12-16 hours with moderate usage of web, email, facebook, and heavy twitter) and its configured the same was as my android:
1) wifi is on when I need it (maybe 20-45 minutes a day for some marketplace downloads or something)
2) location is always on
3) screen is set to manual, low and 3 minute time-out
4) I have 3 IMAP email accounts that check between every 15 minutes and every 30 minutes.
5) I have a VERY active twitter account that updates every few minutes (not sure exactly as it doesn't appear to be live tile integrated)
6) facebook and google sync
7) HTC HUB is usually running updating the weather and stocks as often as it likes
8) dark brown theme
9) ringer off and no haptic feedback
Hope that helps anyone.
I do agree that the HTC supplied battery is sub-standard. Does anyone know where I can see what the battery percentage is acutally at? I only have the icon in the top right.
Just as a bit of information, my HD7 gets significantly better battery life than my sister's Galaxy phone. Also, those of you removing the SIM, make sure you also enable airplane mode, incase the phone continues to still search for signal... Battery size isn't as important as power management, though I do agree I wish we had a bigger battery on our HD7s... we might have sacrificed a little space for it though...
I think the battery meter is off. After about an hour of playing with Netflix, Zune and watching videos with the ign app my battery meter indicated that I had a lil juice left. I went to sleep without charging the phone. I was sure it would be dead when I woke but it wasn't. I was able to get about 2 more hrs out of it while using the Zune player streaming a playlist I saw.

There is no third party multi-tasking in WP7 and Android Users usually have more apps/services updating stuff in the background. Yes, WP7 will get better battery life than lots of Android Phones and even theHD2 with the same battery in it due to that simple fact along, nevermind all the other exceptions and the obvious disclaimer: different use patterns are different.

I have ATK or whatever it is installed on her phone, not sure if the AMOLED screen uses more juice though
Don't get me started on task killers and android. ATK may be causing the poor battery life. Those process and apps you think your killing are just gonna restart and cause more battery drain. Android does not need task killers. I suggest trying auto killer wich tweaks androids internal memory management to be more or less aggrsive. Phone must be rooted though.

I won't have much luck with that lol, her phone, her rules... I might convince her some day though

Ughh battery drain definitely too fast.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.
Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?
Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.
Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.
I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel
From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.
Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise

Battery Reducing Quickly?

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help
If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.
Sent from my SM-N975U using Tapatalk
Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

Wow that is unusual. Do a search for "sleeping apps" in setting and add all the apps you don't need running in the back ground. Also in device care > battery you can see what app is using your battery.

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again
AOD typically consumes 1%~2% in my past note devices(7,8,9)

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.
Reporting my battery life. I guess this is truly an all day device.
Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

In an hour? Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours
I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.
Is everyone having problems on Verizon?
Quote " Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use."
Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.
