[Q] Awful battery life. Should I replace my phone?

As I posted in another thread:
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.

I am rooted, S-OFF, using the Sense Modaco ROM. Battery usage was no better with the Stock Bell Rom before rooting or S-OFF.
My main concern is the screen flickering at low brightness. it's as if it's unable to decide on a specific level of brightness and makes me question if it's actually saving any power.
I set my phone to Auto brightness and I am going to see if that is actually worse of if it's on par with 20%.
Ugh - just realized there is another thread pretty much all about this. I thought it was a different issue. Still, does anyone know if there is a better batch of phones or something? I have a FutureShop warranty so it'd be easy enough for me to replace if it will actually provide a solution

No-one has posted anything, to my knowledge, about a different batch of phones having better battery life. I would check out the other threads about battery life (including those on the G2 side too) and see if you can get yours to last better. But it could just be something faulty on your phone/battery.

Auto-brightness would make it even worse..because there is some type of bug or something that isn't making it function like it should. I was also getting terrible battery life until I followed some of these steps: http://www.goodandevo.net/2010/05/20-tips-to-improve-htc-evo-4g-battery-life.html
Biggest killers are any widgets that are constantly updating..or facebook/twitter apps that are constantly updating. As well..i recommend SetCPU to underclock your phone when your screen is turned off. This should also help with conserving battery life along with some of the steps provided in that link.

I am considering waiting a month or so and then having mine replaced. Unless I managed to figure something else out. My HTC Legend had better battery life.

The reason I want to try auto or higher brightness is to see if lowering it was actually saving me any battery life. I am curious if there's a driver or display issues that causes it to use the same amount regardless of the setting. So far I don't seem to be running out any faster @ auto than I was at 20%, but it hasn't been a long enough time to tell for sure.
Also I am unable to do the battery tip for the evo because once I turn off the phone and go to charge it again, it's instantly green. But I am going to try it anyway even though it's green.
Since writing the first post I used the OC module to get my phone to 1.2ghz. I have SetCPU set to run on boot with the onDemand setting. I have a profile that says to slow the CPU when the screen is off. From what I've read it doesn't make a ton of difference with this particular phone, but we'll see...

Yep, that's what I found too, when you try and charge it thinks it's already charged and goes green straight away again. But as you said, worth a try.

I just wanted to report back and say that I had my phone replaced. So far so good:
- No screen flicker issue at low brightness
- Battery has lasted nearly 20 hours with moderate-heavy use (played NFS Shift, setup basically everything on the phone after rooting, installed all my apps, backups, flashed some roms, 20+ texts, 3-4 short calls, showing people random apps.)
If it's not all in my head then this is definitely much better now!

Curious. It seems that everyone who reports the screen flickering problem has poor battery life.
Defective displays?

I feel my battery life is pretty bad as well. I've unplugged the phone this morning at 7 AM. Now it's 2 PM, and I'm at 37%. In between, the only things I've done are: send/receive a few emails and chat on gtalk. Brightness is at 40%, animations are turned off, wifi and gps location off. Using latest Cyanogenmod (6.1.1) and have no screen flicker issues
Edit: 17 minutes later, it's now at 27%

How long have you had the phone for?
Initially the first few days I got the phone, battery life was really bad, could drain in a few hours.
After a week or two of use, I now have reasonable battery life, the phone can last all day with light usage and still have lots of juice left. Actually I think if you make a few calls and a few txts, battery could last 2 days. If you play with it, one day for sure but you need to plug in over night.

(if you're talking to me) It's quite new, just picked it up on Friday actually. Also I've kept on researching, and it seems that poor coverage (like I have at work, from 7 til 3) tends to drain the battery even more, since the phone keeps switching between HSPA, 3G, etc.

I had my first one for about a month at least. This replacement was from Saturday.
Today I've had my phone unplugged since 8am, it's 5:30pm and I have 45% battery left, but the screen is the #2 user. Standby is #1 @ 40% of my battery usage, due to over 4 hours of time without a signal. The screen is only 24% and has been on for 48 minutes. Voice calls is #3 at 23% battery usage, with 23mins of calling.
My other phone would have died by now.
Also I spent an hour of streaming bluetooth audio to my car. Bluetooth doesn't even register on the battery usage. I've never seen it use more than 2% and it's always on. I am not sure why people say it uses a lot.

Just want to share my experience.
I too had poor battery life. Stock Bell ROM. Got to 3:00 pm and it used to die. Use this for work. Pushing data all day from Exchange server, bluetooth on all day because I'm in and out of the car, talk on average 30 minutes per day, texting, surfing, tethering, blah blah. Believe it or not, my old Omnia II would get me thru the day no problem.
I was also tempted to return it. But I decided to try a few things. Installed Set CPU and a task killer at the same time. Shut down as many tasks as possible on start up. Widgets and accounts, except Exchange-push, run and sync every hour. I get about 40% battery by dinner. I am happy now .

I'm quite happy with my Desire Z's battery life, It lasts for about 36 hours with moderate use. I have Juicedefender and Ultimatejuice installed, data or wifi are opened only when an app needs data connection, this increased my battery life by 10 hours or sth like that. Nice app.

I had terrible battery life until I went overseas. It is a stock Bell ROM, but I arrived in Spain Monday and am using a Spanish SIM card.
My battery life has increased from 14 hours with Bell's 3G signal to my current 27 hours and 35% remaining battery using GSM and WiFi always on. Funny thing is that no matter where I am it says the screen is by far my biggest power drain.

Where did you buy your Desire Z and how did you get it replaced? I'm with Bell and they would take mine to send out for "repair" but not sure if that will do anything. This will take 3-6 weeks apparently and I'm not sure if they it is worth it.
I'm running 10 hours with that I consider fair usage (few calls, text, map/gsp, and facebook.) My display is the highest battery usage at 60% and on for about 1:45h. I'm very disappointed.

Hey,
it's the same with my G2.
Max 24h.
I've standard ROM installed.
No WiFi.
Brightness to about 30%.
Juice Defender is installed and I'm surfing and just the regular stuff, but even if it's just in standby, it's taking a lot of power (display takes most)
Best!

I bought mine at FutureShop since I didn't think Bell would let me without buying at least a month of service (or being an existing customer). I also purchased FutureShop's extended warranty which is how I was able to get it swapped for a new one so quickly.

I use the extended battery for the evo. Lasts about 1.5 days with ass loads of use. Just have to trim the plastic edges a bit.

I have a couple of those red chichitech batteries but I wasn't able to notice any improvement with the problem phone.

My Desire Z also has a flickering screen at lowest brightness, and with moderate use it dies after about 12 hours max. Even on lowest brightness the screen ueses 59% battery. I rarely manage to make it through the day without having to charge the phone. Im on stock ROM with latest OTA (1.72) btw.
Gonna have it replaced next week just cause of the flickering screen. Has anyone tried the 1700mAH battery from seidio?

[Q] Utterly HORRIBLE battery life across batteries and ROMs

Hey XDA
I'm having absolutely HORRIBLE battery life with my GIO. I've gone through extensive testing to find the root of the problem but nothing seems to be the cause. So far i've had to charge twice, maybe three times a day.
So here's the story. A couple of months ago I noticed my Gio's battery was dying quicker so I flashed another rom [Particle Mod] over it. I was happy, until I found out the problem persisted. Then I flashed a 2.3.7 Cyanogen mod, the battery still wasn't lasting and the battery life was only slightly worse owing to CYMOD.
I then flashed the GALAXYICS beta, and it's getting even worse. I've even bought new 1600mAh batteries to see if it was the battery's fault. Apparently not, so I went back to stock for a day or too to see what it was like, and I was still lucky to get 12hrs out of it with featherweight usage.
I simply do not know what to do, I've tried numerous battery mods [flashable zips etc] and they've only done a tiny bit. Lately I've been playing with clockspeeds but it seems to only make a difference if I raise the minimum speed, the extra top end performance is nice though.
So, what I'm saying is this normal for a Gio? Is it a hardware fault? software? 4th dimensional? I'm at a loss, and I think the infamous Samsung cell standby drain is to blame.
Attached is screenshots of general battery screen, Cell standby and the Graph. I've been switching between 2G and 3G, Airplane mode on and off, and listening to music for an hour or so and It seems to have utterly crippled the device doing simple tasks, and I've done EVERYTHING to minimize the drain by lowering screen brightness to %0, turning off vibration, animations, wifi, GPS, BT, radio, everything except google contacts sync and a couple of root things in between like deleting the batt stats.
The new batteries help somewhat, but I still can't last long enough for a single school day... FFUUUUU!
I really don't want to have to buy a new phone, I'm only 14 so I can't work to get one, and I can't just ask my parents because then I'm just being a spoilt brat. I want to make this phone last as long as possible [Until I can work for a Google Nexus or something] and the battery isn't helping.
Thanks for reading.

Yeah you're a spoiled brat. This is not great but not extraordinarily bad. My epic 4g touch spends the day on the charger.

Well, it seems to be all right with your battery. And your '1600 mAh' battery was just a fake. A lot of people get scores like this

What I am worried about is not so much the capacity, it's the RATE at which it drains. I see a lot of "stair steps" on my graphs so I'm not so sure, especially when checking the other phones in the house "a Galaxy Ace and 2 HTC Incredible S's] they seem to have a more consistent curve, I notice my batteries will drain by as much as %5 in half a minute, which is either a reporting bug or inconsistent strain.

Have you tried to do a wipe and test it with no installed apps?

Do not trust the "stairs", it is just bad reporting (as you said).
In my case when I switch on 3G or WiFi, it happens that the battery drops by 10% instantly.
The only value that is relevant is the total duration between a full charge (100% charge + several hours still plugged) and the "low battery" indicator.
According to my own experience, the things that drains the most are :
- 3G network : this is the main factor, by far.
If you can, try to stay in 2G mode most of the time, switch to 3G when needed, and as soon as not needed anymore go back to 2G.
- WiFi / BT
If you switch On/Off very often, or is always On and you moves very often (changing hotspot), then WiFi / BT will be a very important battery drain factor.
- Multimedia
Videos / MP3 drains battery a lot.
If you can, switch to "airplane mode" or switch off the phone during night.
Finally, with 3G / WiFi / Multimedia usage mix, a "One Day" autonomy is good.
I'm sorry but you will not find any smartphone that can pass "One Day" with that usage type.
With my own usage (very few calls, sms, wifi) and with above tricks, my Gio lasts 4-5 days.
PS : As you mentioned, available ROMs are very unequal as far as battery drain is concerned.
Stock ROMs (and moded ones like Adrenaline) are the champions of battery life, while ICS ROMs are the worst.
CM7.2 ROMs are in between.

I agree with Vilo76. When you don`t have wireless or 3g, or play any music/games, you can actually get a few days of life from your phone, but if you do some of the stuff i just said, the battery life is going down like crazy...
The only think you can do to get some bit of juice out of your phone is if you format your battery, but actually that is just for a better battery reading, not actually extending your battery life...

By the way, I can't figure out why phone manufacturers don't use more long lasting batteries ...
There are many many examples of batteries that are about the same size as a phone one, but deliver way more mAh.
Among others :
- House wireless alarms keypad batteries are the same size but can be as much as 3000mAh ...
- Classic cylindrical AA or AAA accu can be as much as 4000mAh ...
While a typical phone battery hardly ever exceed 1500mAh.

Okay, I'm back and I have some results for today
3G Is DEFINITELY using more in Australia on idle, while 2G is a bit less brutal
There is something cause my phone to wake intermittently, I've turned sync and location services, and killed any apps that may be checking the net etc, but it's still waking up with screen off.
---------------------------
Today I decided to do something bit extreme, I ran the phone an airplane mode all day with the original "dead" battery, I only lost %20 all day with 1hr or so music usage, phone standby is up but Cell standby isn't there at all [Obviously].
Something's telling me that's it the cell radio and whatever is waking my phone up is causing the suck. I'm upgrading to GalaxyICS CM9 beta10 today with a full dalvik, battery and cache wipe, so we'll see how that goes
----------------------------
MORE NEWS
Good news this time! I've installed a Cyanogen Mod 7.2 on their [The one that's updates through Goomanager] and the battery is holding steady at 100 idling for 1hr on 2G.... Not sure if I have to calibrate but I think I've fixed it, it's working better than stock!

Your HOX battery life experience?

I see countless comments with people complaining about battery life not being good enough in most threads, and it being affected positively/negatively by updates.
I'm aware a lot of ROMs can have a very positive effect on battery life but I am more interested in the general overview – your battery life's life if you will! The reason I ask for your experiences is that I would like to qualitatively collect a bit of information from a fair few people and see what's to be seen.
It's worth noting that my latest HOX's battery life is exceptional and I believe it's down to a simple life/career change. It's really nothing new to someone who knows their fair share about batteries however I would be interested to compare.
So, list the times you wake up, take your phone off charge, put your phone back on charge, and go to sleep. If you can it would also be nice to know what your battery percentage is at certain points. It would also be interesting to know what hours you do on an average working week and in what sort of work environment (home/architect, office/marketing, shop/clothes retail etc).
If anyone can remember the things off the top of your head, even rough estimates just chuck then in the thread. I will then compare them all to my own personal habits.

Sent from my faster than SGS3 HOX.

Personally for me ICS was 4.0.4 was perfect, after update to JB it's really bad. On ICS i was loosing 1% of my battery during whole night on JB i can even loose 10% ; d. Overall battery drains faster during usage... all stock.

There's already a thread for battery stats.

Fantastic. I'm more interested in people's actual habits not stats about their battery because it only tells one half of the story. Like I mentioned this is more of a qualitative approach, so less battery stats.
I should of assumed that most people would be like more yourself so I will get straight to the point.
I have the benefit of working at home which means I can charge my phone whenever. I'm not forced to charge it over night; having it over charging for excessive amounts of time. I charge mine in the day and as a result I'm conscious when it hits 100% – I then unplug it. Other than natural degradation, I doubt I have ever damaged my battery in any way which has left me with a great battery life.
I was quite interested if most people charge their phones at night, go to sleep, unplug their phones when they wake up etc. This will severely accelerate the degradation of the battery.

well for me, ICS was bad...im using custom rom and various kernel to see which has the best battery life...all bad accept ncx 0.99....well some of the time its ok but some not...the battery percentage in ICS if not using will stay at 1% but for a 5 minute use, it will drop 10%...but amazingly, if you keep using in screen on, wifi or whatever, it will not drop that fast, well for me its ok....but now i have updated to JB still in stock, and the battery life is great.. i have watch HD movie using MX player in 2 hour and only drop 20%....when in ICS about 80%...big difference....i think stock kernel is best...

Well for me it's decent i mean yes it could be better but it's okay... heres my usage: i take it off the charge around 10 am when i wake up or so and it's off the charge till the next day morning with avarage 45-50% battery left and screan on time avarage 2:30 hours - 3 hours, sync with FB , hotmail and weather is On all the time as well is the wi-fi even when i sleep, my reception aint so great tho , around 2-3 bars top 4, 2g network, anyway my tops on the screan time would be around 6 hours with around 30% brightness idk how that guy managed to achive 6hours 20 mins on a single charge on medium brightness , could be jelly bean or maybe partitial charges ( i'm on ics btw ), anyway hox battery aint so bad as ppl may think, besides if you're lucky enough you'll get hox + battery into your hox ( 2100 ma ) which should provide avarage 6 hours + screan on time, tho i bet we could get around 8 with that battery. Hope this helps.

Ive got arhd and i got to say Im happy with my battery life, first I wasnt, when I went through a couple of charge cycles it got better and better. Now I can do 3.5 hours on screen time playing games and use it for atleast 24 hours with a mix of everything with watching videos to on the bus lol. So mines has been really good.

Battery has been pretty bad on any ROM. Now that I have ICJ421, my battery is near perfect. Yesterday I got 14h with 3h22m Screen On time.

LG G4 - Pitiful battery life

Hello all,
I recently purchased a LG G4 Back In July , on Verizon, switching over from A Galaxy Note 3 (Tmobile). Honestly I really really like the phone, but I think the battery life is pitiful for a $700 dollar "Flagship" phone. I mean not once has it ever lasted the full day. I had to buy a spare battery kit, with 2 batteries, and days when im out from 6am to late at night, I go through 2 batteries, and have to put the 3rd one in. I mean , this is simply unacceptable for a phone like this.
Also, the camera is excellent WHEN it works. A lot of times, it doesn't take the picture right away, there is a delay, and many times it falls out of focus. This is certainly not the high quality camera they advertised.
I am hoping there is a way to fix these 2 issues, mainly the battery issue though because it is awful in my opinion. Is there any tweaks or fixes for these issues?

You've barely given any relevant information other than how unhappy you are with the device, so I would suggest that you elaborate on that.

You could inform us if you're a heavy/light user, if you keep NFC, LTE, Bluetooth, Syncing, Wi-Fi, on during the whole day or maybe if you are used to 100% brightness display. Maybe you should check in your settings what is draining your battery and provide us the info.
I'm having a pretty good experience with the phone so far. It surely lasts a whole day with 3:30 to 4h SoT. I don't even need/have a spare battery.

One person having an issue doesn't mean it's not a great camera. You'll find it's likely still the best flagship camera of any OEM.
Battery use is so dependent on which apps you run, which mods you have, how often the screen is on, what brightness, signal strength, wifi, bluetooth, etc etc etc...

I came from a galaxy s3 and reckon the battery on g4 is awesome. I use it solidly on internet for 2 hrs a day (to and from work), check messages etc through the day, usually internet at lunch. And then evening time check facebook etc over WiFi infront of telly.
I unplug at 6am and plug in around 11pm with around 3% left. I bought a 2nd battery and only needed to use it twice. It has to be how you're using it.

13 hours on battery for me today and still 71% left. Light usage but it does illustrate that the battery life can be excellent.

of course, you can get excellent battery life on every smartphone - just put it in aeroplane mode..
I get MAX 3h of SOT time on my G4 - this is with fixed brightness at 65% (at all times) and only wifi and 3g enabled (NFC, bluetooth and everything else is turned off all the time)
to be fair I have yet to own a smartphone that lasts me more than 4h SOT..
the thing that annoys me the most is the broken knock code used to unlock the phone - it works 20% of the time at best
its a completely broken feature LG has not properly addressed since launch of the device (I am on V10e software)

There have been numerous firmware updates since. Have you ever performed a full factory reset after getting those updates ?
If the answer is no, then this is one potential reason for poor battery life. What you could try is to clear the system cache in recovery. Note, i said system cache not apps cache. Idea here is when updates come in there could be conflicts and it causes the system to work harder. clearing system cache might help, if it does not then the only option is a factory reset and then a manual install.
not restore. You install apps in batches, monitor, then install more and so on. You can restore contacts etc. but apps themselves will have to be reinstalled. Sometimes apps go rogue and have to be reinstalled. Its hard to tell which app is causing the issue. Otherwise you could just reinstall whatever app that seems to be taking up more than it should be.

How do you access the net. How good is your signal. What are you doing when you access the net.

What types of shots are these. It can happen with portraits some times. It will focus on the background behind the person instead of the person and the face becomes softer and the background very sharp.
For this set focus little above the chest instead of the face. If they are wearing dark clothing this will cause other issues so focus on something else at equal distance that isn't dark.
Always check the shot at the pixel level soon after you took it. Rather than at the end of the day.

Just to clarify: I had everything turned on for those 13 hours - wifi/data/bluetooth/GPS. I also made 2 phone calls and did a bit of Chromecasting using the BT Sport app for a couple of hours. Or to put it another way, I didn't take any measures at all to preserve battery life.

I used to complain just like you're doing OP ( @dredmentia ) and fixed it all with a Zerolemon battery .
Is the phone bulky/no leather back/not easy to handle... , it sure is but if battery life is crucial then it gotta get fixed.
End my day anywhere between 7 to 13 hours of sot depending on WiFi or 4g and high CPU freqs, tried light usage and hit 3 days with 12 hours sot. Snap/insta/twit/fb/periscope/... Nothing kills this battery in a day.
When and if we get a kernel I'll move back to factory battery at least then I know I'm in control of how CPU works coz while optimizing the phone for wakelocks that's the only thing I have no control over...
As for now I'm just trying to burn thru this battery every day so I can charge it every night...
Last phone was a Z3 Sony and that really grabbed my attention with its battery life in stock form, almost too perfect, Almost.

Did someone seriously just ask me if I kept the brightness on the screen at 100%???? Obviously im not doing that, im not some idiot. I know the screen eats up most of the battery. I keep the brightness extremely low way under 50%, or on auto., The battery still last a short amount of time. Its not acceptable

[A520F] Battery problems

Hi guys!
I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

You could try the naptime app. But I don't think my battery life is any better than yours.

The a5 2017 has a famously good battery life.
I am not a heavy user - make and get few calls and mainly use it for receiving emails and a few texts plus a bit of web browsing.
Occasionally listening to podcasts.
3 days battery life is easy for me - reckon I could get 5 days if I just left it sitting quietly.
If it's going flat quickly even when switched off, it sounds like a fault somewhere.
Don't know what else to tell you.

I never tried letting it sit, but if I just left mine alone it would last for days too. But if I am gaming on it, it will go down to around 50 percent at noon.

wow - 3 days life battery!! I can hardly get to 2 days, without heavy us - but I would never try to change the battery -> sounds too complicated

One thing that is worth looking at is the Always on Display (AOD).
I found it sucks a lot of power despite the claims that it 'doesnt use much'. It seemed to use around 1% an hour - I guess thats around a quarter of your battery in a day. So unless you find it useful either turn it off - or set it on a schedule for when you actually want it to be on.
Battery life is always sujective and depends on what your phone is doing - gaming will burn through a battery like nothing else.
The OP said the battery drains even when the phone is switched off - That sounds like a hardware fault. The battery will gradually drop when switched off - but it should take months for a healthy battery to drop much if the phone is switched off.

1 percent an hour doesn't matter to me lol. I am a heavy user so I charge every day anyway.
