Battery Life on IIs

Hey what have you guys n' gals been getting off your XDA IIs for battery life. I am away from home just for one night this week, and have forgotten my charger (Must get a sync n charge...but where!!!!) I'm only using PDA functions and Duality Email....and battery is already at 83%
Will it last 48hrs!!!!! We'll wait and see!

Obviously using it as a PDA does use more battery life.

With my phone 'off' (well pda bit off) and WiFi off, over a 12 hour period of inactivity I'll use maybe 5% of battery, so when it comes to bed time your battery use will reduce.
if you're away from chargers I'd advise keeping wifi off, it's the battery eater portion of the functionality. a little light GPRSing shouldnt hurt if you need email, bluetooth isnt a big issue, but if you need to last 48hrs, dont touch the WiFi :twisted:
Also I have noticed that my battery goes from 100-95% REALLY quick (like 10 mins with only BT on), but then takes maybe 30 minutes of wifi browsing to use a similar 5% in the 50% range!?!? non-linear battery consumption maybe? Might be just mine.

I've noticed the same but, conversely, when charging, it takes longer to charge the last five percent than the rest. So, I put it down to the Battery monitor API. These things are never 100% accurate.
As for battery life, two days from normal useage and three and a bit days if I'm careful. I have no problems going for a long weekend and not taking the charger as long as I have no plans to use it intensively.
I find reading an ebook with mobipocket also kills the battery at about 10% for every hour and nearly treble that if I'm listening to music at the same time.

1 Day, its usually down to < 30% come time to goto bed. But then, it gets well used.

So, the question has to be asked..... Who has the charger by the bed?
/me raises hand.
Sync cradle is at work... which charges too.

Battery Life on XDA
If you turn ON flight mode you will find battery life will improve but you will not receive "always on emails".I've got a feeling the phone wont work either (i don't use mine as a phone so not sure).I know when you turn flight mode off again you will have to enter PIN no.
I used this method when I was in hospital for a night and they would not let me charge my XDA.

yeah : flight mode = turning off the phone part
I have a brodit cradle in the car , charges it extra while commuting

As default when you get the phone, it will ask for a pin number. This can be disabled though through the software!
Flight mode will of course save battery - like said - its not using the phone functions which are probably the most battery draining.

I have to use my charger twice a day but i do cain it as my job is so ****ing boring! i hope to god someone invents a....
Solar panel charger
so i can go campin in wales on ma scooter and not need to sneak my phone into the pubs wall plugs all the time

I have a brand new M2000.
I took it off charge at 08:00 this morning.
I got to work at 09:30 and started using it.
I had bluetooth on with headset and I was using wifi on and off.
I started getting low battery warnings at 15:00.
That is very poor

I have BT on and can run from Thursday night through till Sunday without a problem. Though I do get worried about making calls on the Sunday. If anyone has a description of how to convert an XDA car cable to XDAIIs I would be gratefull.

O2 Orbit - any experience on Battery Life

Just wondering how the Orbit fairs on battery life before needing charging
is this a better XDA battery life wise than its predecessors?

I listen to the radio all the time on my P3300. My talk time is about 1/2 hour per day. And, of course, some occasional usage as a PDA. With this usage pattern, the device looses about 30% of charge per day. Yesterday at night, after having the device fully charged, I used it as a GPS navigator for about an hour and than did some browsing on the internet via WiFi. Today at 11am, I found the remaining charge to be 68%.

Well I'm new to XDAs and having only had my Orbit for 2 days I'm not overly impressed with battery life. I fully charged the battery overnight and today form 8.30am, I have used around 1 hour of talktime, 15 minutes of internet via wifi and a wireless router and used terminal services for remote access for another 15 minutes. I have probably used it another 15 minutes adding tasks and calendar entries and it shut itself down at 9.30pm tonight.
I consider my useage to be on the low side but if I use it to it's full potential, I can see me having to recharge it twice a day at this rate.

IME experience the battery life (after the first flush of acquisition ie constant fiddling ) is waay better than any of the phones in my sig (exception the Motorola A1000), comparable to my Nokia 6280.

well..to maximize ur battery life..i suggest to put the brightness of the screen to da least..i hav done dat..n i must comment im pretty impresed with da performance..3 days n kicking with 10% still to go....!!

Hi,
Though this is not entirely relevant, my MDA Compact 3 ran for 7 hours with continuous use of Memory Map GPS mapping software (backlight set to go off after 5 minutes).
Regards

I'm actually very impressed with battery life.
Much better than my last Pda (mio P550) and Co-pilot (and i-go) use so little power compared to TTNav(5) Ie dont need to plug in charger on a long journey !
(TT nav ate the battery in about 50mins !!).
Obviously it depends on use and with all the xtra features, GPS, wiFi, etc to play with it can run down faster than a simple moby. Tip: turn off wifi, bluetooth and anyservices not using (easy to do with the o2 shortcup installed in bottom rh corner).

Battery drain with Desire on alcohol

Hi. I know there are hundreds of threads on battery usage, but I felt I have a special story behind my test.
Lately I feel that my battery life has decreased, but I would like some second opinions on the case.
It's over a month now since I received froyo OTA, and I had some suspicions that my battery life went slightly down after that. I used it more to test the new features, so its hard to really know. However, the big problems occurred a couple of weeks ago.
At a party with a friend of mine, a friends friend literally pulls my Desire out of my hand and drops it into a mug of beer! As a joke!!
He had heard me taking about my Nokia 3720 earlier and decided to test it. However, ignorant as he was, he did not see that it was A DIFFERENT PHONE I was holding!
So it took 2 seconds in the mug, and the screen went black, and the phone was dead... Or not really, I took it out and dried it of with my t-shirt, turned it on, and the screen went garbeled green on me...
Decided that it was best to leave it alone, so I took out the battery, SIM and MicroSD, dried them off, put it in my pocket and continued the party.
But I have to admit it was kindof a partypooper for me...
Well, later that night, probably 3-4 hours later when I got home, I inserted the battery and tried to turn it on.. Screen turned on with the familiar white background, and green htc logo.. and some garbeled green at the top, argh...
I took the battery out again, left all the pieces spread out on the kitchen-counter and went to bed.
The morning after (or should I say afternoon ) I looked at the phone, it seemed as it had dried out over the night. So I put in the MicroSD, SIM and battery, crossed my fingers, and turned it on. And it worked fine, like nothing had happened, phew!
But some days after, I am sure that the batterylife has decreased quite a bit, seems to not hold a normal 12-14hour day with normal use.
I did at one point post-froyo (pre-drowning) have it running for 2 full days before charging, approx. 40 hours, not very much usage though..
So, I decided to test it starting yesterday evening.
I let it drain fully (turned it on 1 time after it died, and let it die again). Charged it while turned off, and unplugged it and turned on after approx. 1 hour of full charge (green light).
Now, I have already ordered a new phone (a Streak is on its way over the North Sea as I write this . But I wanted to do the test just for the heck of it.
My girlfriend also has a Desire running Froyo, and I notice she uses her phone WAY MORE for gaming and stuff, and only charges a little more frequent than me.
They are both AMOLED phones, I got mine in Feb, she bought hers in March.
So, here comes the timeline:
@23:30, Turned it on after fully charged, went through all homescreens to activate all widgets. Did not run any programs.
I have no specially data intense widgets, only email and weather (3hr sync). Wifi off, and 3G (H) on always, no active background.
@08:00, On my way to work, Battery indicator (i use *#*#4636#*#* to check battery status) at 88%, recieved 1 email during the night.
Battery usage says: 49% Cell standby, 49% phone not in use, 2% android system.
I have noticed my phone struggling to keep connections while travelling even short distances(pre- and post-froyo), maybe a little worse of a problem post-froyo.
Did not happen today though!
I often need a reboot to get the connection back (Flightmode often works 1 time, but not 2 times. does not activate the second time I try it, just hangs...)
It's not only the data connection, there is no cell reception at all (apparantly).
Maybe I should start a thread on that also, but it is not a big issue for me (this phone is on a free use data plan, almost never use it for calls)
Dataplan here in norway costs around 50$ btw, no other extra costs for tethering and such in norway
@09:45, at work, recieved 2 more emails. now @84%, on EDGE network. battery usage: 53% Cell standby, 45% phone not in use, 2% android system.
not that bad actually... 10:21 "on" time, with 34 minutes active-use time.
Will try to leave the phone alone some more, and do some surfing on it around noon.
@12:55, still at work, used the phone for surfing and gReader for 25 minutes, on EDGE network. Downloaded a BOL revisited episode (podcast), I usually listen to an episode via bluetooth streaming while driving to/from work.
Now @67% and 35°C ( I noticed an temp. increase). Cell standby 47%, Not in use, 41%, android system 9%, screen 3%. uptime 13:35, waketime 1:07.
It connected to H (3g) the last 5-10 minutes or so of surfing. Turned on Wifi when I was finished, to see if I notice any battery decrease.
@14:25, did another 15-20 minutes of surfing, this time on Wifi, now @62%. also was a quick trip via google maps with gps on. battery usage states: Wifi usage 3% and google maps 2% already.. seems they use a lot of battery in a short time.
Wifi is set to turn off after 15 min of inactivety.
TBC....

Read that. Do a teardown and clean everything, you're out of warranty anyways.
Most likley a drop/smudge of beer etc inside short circuiting something and you'll have a slow, but increased battery drain from that.

thanks for giving me a heads up on that!
Not sure if I will take the time to fix it though, I'll have to see how much I miss it when I start using my Dell Streak

@15:35. On my way home from work. Writing using voice recognition on android. Battery level is currently @ 46%. Downloaded several emails, and 1 reply. Now connecting bluetooth for BOL streaming.

Okay now i'm home, after 40 minutes of Bluetooth streaming battery is @36%. Stats are: cell standby 39%, not in use 34%, android system 15%, screen 5%, WiFi 3%, Bluetooth 2%, maps 2%. Times are: 17:07 total, 2:49 awake.

@18:15 Surfing for 15 minutes now over 3g, and battery icon is orange.. level: 27%, awake time is now just over 3 hours.. I think it has held up quite good today, but I have really not used it as much as I normally would. And I also have a suspicion that using less WiFi helps a little on battery. Previous I have used WiFi always on to save 3g usage, but maybe it decreased battery.. anyone with a comment on that?

@18:45. Slight use of xdaapp and browser, now @18% and sinking rapidly :s

@19:45, well my battery has just about had it for today, so this will be my last post. It's now @11%, have used it a little the last hour, but only light use..

Problem With Battery

Hey guys, I just got the droid incredible 2 and I first had the LG revolution but the 4g and the screen size made the battery drop down quick. I played with it for 20 minutes after it being fully charged, changing settings, and the battery went way down to about 80%. So I exchanged it for the HTC Incredible 2. They told me the batter was way better.
I went to the Verizon store to tell them the batter dowesn't last as long as expected. My Iphone 4 would be on all day, texting, pandora, email and web browsing and I still came home from work with battery left. My droid gets used from 7am to 1pm and its pretty much dead by then. They made me change the background data off, sync only email and weather, and download juice defender.
The batter still dies by 12:30pm after charging all night.
I have read all over people are getting excellent battery usage but I don't really know what to do to get the same. It is not temp rooted. Any ideas? Also, at work, in the building the data coverage is not so good so I usually do nothing but text on it and it still dies by 1pm.

I can't really say how well mine would do on the standard battery because I bought the extended battery immediately after getting the phone. I've been unplugged almost 15 hours and have 38% battery and I have sent/recieved 40-50 txts, 20 mins phone, browsed internet for 30-45 mins, played games around 30 mins, and listened to pandora for around 45 mins.
I would recommend the extended battery, it's $50 at verizon and I haven't even come close to killing it in a day.

Does the extended battery make the phone bigger? I'm thinking it would be thicker on the back. Would it have any drawbacks as to cases and stuff like that?
I'm not sure why mine is so bad, prolly because I am in a secure building and signal doesn't get through constantly. I'm surprised, I thought my iphone had bad battery.

the extended battery does have a thicker back. and yes, there are currently no cases for it, so there would be an issue there if having a case is very important.
as to your current battery, if your in a biulding with bad signal, that will most defintiely affect your battery life as your phone will have to use more battery to try to find a good signal. additionally though, the phone battery does seem to improve after about a week of charge/discharge cycles. not sure why this is, but i have seen it on my phone and seen many other report the same.

The battery sticks out a little more than 1/8th of an inch I would say. However, IMHO it protects the camera lens and flash lens from getting broken and I never really like using a case anyways.

I have amazing battery i charge it to 100 percent unplugged after then go to school texting 100-200 average everyday internet music by the time i get 3:00 i still have 80-70% and i'm 13 so imagine how much i use it and it still stays at that percentage

Having a phone in a building (or anywhere) the signal is weak is a drain on your battery. If your iPhone was with AT&T the signal may have been stronger where you work than with Verizon and may have therefore contributed to better battery life.
Also, if you didn't FULLY charge your DInc2 and FULLY discharge it right when you got it, you should really do a factory reset and immediately do the following:
Charge the phone for at least 8hrs with the power off, unplug for a few minutes, plug it back in. The light should only remain red for 10-20 seconds before turning green, otherwise this unplug-plug part should be repeated a few more times always letting it remain on "green" for an hour before unplugging an plugging back in.
THEN power up and use the phone until it shuts itself off because the battery is drained. Let it sit for a few minutes, and turn it on again. It should sut itself off again pretty quick. Let it sit, turn on again. Do this until it wont power up at all after sitting untouched for a few minutes and your battery is then fully discharged.
Now you can plug it in and start the charge part of the cycle as lined out earlier. Once the light turns green 10-20 sec after plugging it in again you have completed one "cycle".
This may sound excessive, but I'm kind of a nut about this kind of thing.

I didn't do anything special when I got my I2, am a realtively heavy user, and have an all day battery life. I'm pretty careless with my features being left on.
If you can't get it to last all day, either you are a much heavier user than I am or you do, in fact, either have a battery problem, or a battery calibration problem. You shouldn't need to calibrate the battery algorithms, but I guess it doesn't hurt to try.

I wouldn't say I am a heavy user. I normally text while I am at work and check facebook a few times. I also listen to pandora most times. I work for Vanguard and most people here have Verizon I believe. I was told when I switched from AT&T that signal should not be a problem where I am at. My Iphone 4 would get used much more and it too would have signal problems as well until I turned 3g off but it would last way longer than the droid.
I guess I can try the factory reset and full charge cycle this weekend but I'm not sure what Verizon can do for me either so it may just stay like this

this is bump charging no? (well the part about how to charge it). i spoke to am htc rep that said that bump charging will significantly decrease the lifespan of your battery life and therefore is highly not recommended.

I just got mine on Sunday, but even yesterday I was texting and surfing a fair amount yesterday and went to bed with the phone at 61%...
I am sort of amazed, I think Verizon has taken the underclocking thing and put it to work on the official release... at one point I turned off the screen for what amounted to an hour and when i turned it back on it was still the same battery level.

if your comparing battery life on the dinc2 with 3G on versus the iphone with 3G off there will also be a pretty big difference. if your tuirn off 3G on your dinc2, i would imagine battery life will be similar or better than your iphone had with 3G off also.

No I was comparing the Inc 2 to the Iphone with 3G on. My iphone would also last longer if I turned 3g off and just used Edge or whatever it is called. I don't think I can do this with the droid until it is rooted or download an app to do this.
I turned off juice defender and we will see how it goes today. I don't really like apps running in the background and it was turning off data eacht ime the screen locked.

I think the biggest difference is the verizon signal. The battery on this phone is amazing for an android device. While it is still nowhere near iphone 4 status as far as battery, it shouldn't drain like that. Have them either swap you a battery or the phone itself.
I'm a relatively heavy user. Especially with voice calls and I can go a day and a half easy.
But I also run launched pro with only a couple of widgets. To me sense is a battery hog.
Sent from my ADR6350 using XDA App

What would I do to go about swapping out the battery or the phone itself? Should I go back to the same verizon store? Or call them on the support line and try to get a battery or new phone that way? I have no clue why it is draining like that either, the signal can't be that bad, I literally had the same signal with AT&T in these buildings.

Well, lets be honest, one of the things Apple really puts a lot of time and effort into in their development is long battery life. It wouldn't surprise me to see the iphone outlasting most Android devices.
In any case...
While I don't need to, I do charge my phone while at the office. If you have a desk job then I don't see how this would be problematic. My work day usage includes 2 hours of bluetooth streaming (in my car to the stereo), media playback (music/podcast), and mapping with gps and 3g data (this drains my battery pretty quickly, but that's relative...it's about 15% per hour). Outside of that, my battery drain is quite low.
I only started charging at the office because I like to keep my battery as full as possible in case of extended emergency that requires being away from a charging source. It's that whole boy scout be prepared mentality I have. Besides, if you have the opportunity to charge, why not? It seems to charge pretty quick anyway.

I can charge at the office, but normally I forget the cord at home. Not a problem to buy another one but still. I was just concerned because I hear people getting 15 some hours on one charge and as of right now, my battery is below 50% since I just got back from lunch.

take it back to the store, and if that doesn't work then call. but the store would probably be a better bet as they can give you a new phone or new battery there whereas the phone support, you'd have to wait for the shipment.

Seems as if they were not able to help in store the first time. Rather than have someone check it out, they had someone come over and tell me I should turn off all the sync and data features. So I did do that, but then why did I get a smartphone?

It's possible you have an app that is not allowing the device to sleep. If it can't sleep, it will drain the battery much faster. You might get 8 to 12 hours awake yet idle.
Are you using many third party apps? If so, have you considered going through them, removing them one at a time, until you find the battery doesn't drain so fast anymore?
If you go to About phone in settings, then Battery, the last item will show awake time. This should be much lower than your Up time.

Zenwatch affecting phone battery life?

Hi everyone...
First off, a little background.
I bought my Galaxy S6 a couple of months ago. Battery life on it was fantastic... overnight, I'd drop maybe 1-1.5% per hour.
Then I bought a Zenwatch, which I absolutely love. What a great accessory! Unfortunately, its had a fairly negative effect on my phone battery life. Now, overnight, my phone battery will drop 3-4% per hour. Doesn't seem like like a lot, but over 7 hours, thats a difference of 15-20%.
Last night, just for kicks, I turned off bluetooth on my phone overnight, and it returned to 1-1.5% per hour again.
Is this normal behavior? I thought the fact that it uses BLE should really make this a non-issue.
(Yes, it could be a non-Zenwatch issue, I'll be trying other things over time... just thought I'd start with what seems most obvoius)
Thanks!
