[Q] Is it normal (battery) - Galaxy S II Q&A, Help & Troubleshooting

Is it normal that my battery drops a precent in around 2 hours?
revoulution rom
i heard people with some roms that droped 2 precent in 2 days so it doesnt semms legit

i think its normal but what kind of kernel do you have ?
just ask the people what they use

I drop one percent in 5 mins if screen and 3g on.
Drop one percent if in one hour if phone is idle..
I think my phone is worse

Sorry, 2% in two days is imposible on any smart phone. Do what ever you like, but you won't get that much. This would mean 100 days (even in standby mode) in one charge. Think...

ok im using set cpu now and i idid when my screen off the freq will be 200MHZ and i thought it will consume less battery and i lost 4 precent during the night its 9am here right now
and its pretty frustrating anyway to keep like 2 precent on the night?

My battery performance is not stellar either. I can get about a day (24) hours of moderate use (in this case, i mean the device is in moderate use about 12 hours, while it is idle the rest of the time).
2.3.5 is supposed to drastically improve battery life on the stock version though.

juice defender has actually been a big help for my batter and everyone i've shown it too, like anything android it takes some tweaing but once it's done it's well worth it

i changed the rom to check rom v5.5 with siyah kernel 2.0 i just overclock the CPU and underclock when not in use it saves battery
my question is now if anyone here uses this rom and can find me some themes

[Q] Total Battery Life For You with GPS Active 100% of the Time???

I'd like to know from the folks at XDA how much battery life (in hours) they get once they recharge the battery and turn on GPS (i.e. 100% active with a software--no screen off) until the phone shuts down from no energy.
I'd like to know what ROMS, kernels, etc you're using and how much battery life with 100% GPS with no down time.
For me, I'm getting about ~3 hours with TW 1.3.2 and Bali using Copilot GPS software. Screen at half bright. Battery is reconditioned.........Is this any good?.....

What's the date on your battery? The battery might just be towards the end of it's usable life. Call t-mobile to get a new one sent to you.

I've been having real bad battery problems. People claim 12-14 hours with heavy use and full charge. I get only about 8 hours with medium use ( few calls some texts and some web browsing and pandora) My battery's date is 08.02.2010 and its 1500 mAH . Would you recommend i get a new one and see if that works? I'm running cm7 latest nightly and glitch v11 since i thought glitch would help wit battery life but no dice. Even before i got any roms though my battery life was always about 8 hours with medium use. And thats with no gps no wifi or syncing. Thanks for ur help.

3 hours with GPS enabled constantly? And your screen on the entire time? Yes, that's very good.
I remember I used to have a Garmin that would last ~24minutes after I took it off of the charger.
Constant-running GPS is a massive battery drain. Having your screen running for 3 hours straight is an even bigger battery drain.
Get a car charger.

what worked really well for me is bali 1.1.1 here are my UV settings ive been running my phone all day at 6pm i had 50% and after a good amount of use i have 47% left im not overclocking at all
1000- -25
800- 50
400 -50
200 -50
100-75
when i try going around 100 and up it gets unstable so try these out and tweak em a bit im sure u will have better battery life
Do you use bali 1.1.1 with cm7 nightly too? just making sure it'll b compatible with my setup to . btw funny ur from newark. im from elizabeth =P

A new battery should be free and yes last time i got a new one mailed to me they let me keep the old one too.

What would you say about that..

I am tired of my Amaze, the battery barely lasts me more than 5-6 hours and these drops are unbearable.
I started my day 9am today and the battery was down to 20% at precisely 1:04pm.
Just look at these drops.....
Rooted? Rom?
Chuck Norris can but Walker Texas Ranger can't.
On stock rom and stock battery the battery life on the amaze is terrible.
I have my girls amaze rooted running a custom rom, kernel with setcpu, juice defender and anker extended battery. Now it lasts her all day with out charge in between.

thing is, you should NOT have to do all these tweaks just for a full days use. should be perfect ouf of box
I don't know what you people do, but I consider myself semi heavy user. Today I streamed BT music for an hour at the gym, streamed one movie off Netflix and watched a good few YouTube wrestling matches and had a few calls here and there and a good 50 texts....reading some off the Kindle app and I got 11 hours before a charge.
I get 12-18 on normal usage. Was a light day at work, lol!
Want amazing battery life, then go back to an old school BB phone.....
I am still stock, lol!

This does not look good at all especially the last drop. You might have a rogue app. I would factory reset and start over only few apps at a time so I can identify the app. You may also wanna try other battery like anker.

This behaviour is definitely irregular... Those sharp drops and sudden spikes could be from the battery not being calibrated properly. On average, my Amaze with stock battery lasts me about 14-16 hours with 2.5-3 hours of screen time (lowest brightness most of the time).

Most android phones really need to be rooted so you can fully tweak the battery life. My amaze got roughly 16 hours with normal to heavy use with bullet proof 4.0. My phone I'm using now, the mytouch 4g gets around 24 hours with the same use. Before I would be lucky to get 8 hours with either phone. IV learned that you can either complain about things, do something about it, or just get an iPhone and go away . The beauty of android is the ability to go in and tweak.

averaging ~ 15-19 hrs of heavy usage a day on sense 3.5 rc1.7, sometimes Ill use juice defender to help with the longer work shifts but honestly its a huge difference from when I was stock.
its no different from when I was stock on my g2 to when I was rooted, sometimes you just have to tweak a few things to see a vast improvement.
Morning all,
I just woke up and unplugged my phone from the charger after leaving it to charge all night, right. As soon as I unplugged it, THE BATTERY DROPS 96% IN A MATTER OF SECONDS and I get the less than 5% of battery remain. I was like WTF?!?
I believe I found my problem....
Btw, I am on a rooted stock rom and I would consider myself a normal user. Calls, sms, and emails are the primary uses of my phone.
I am completely stock and get about 16hrs to a charge... I run miui music or stock music app for roughly 4 to 6 hrs a day and surf here and market and a bit of gaming.
I set screen brightness to 20% and keep my internet and blue tooth etc off most of the day....
I desperately want to debloat but I'm holding stock till ICS.
Rogue app sounds right along with the bloat like Google maps and Facebook eating up our batteries..
I also use a task manager to kill on command......
We have a hodgepodge setup of bloatware and settings in stock format... But I'm waiting and earning an ulcer till ICS as I know the upgrade will open the door to real development of truly good stuff

I was getting about 3 hours of battery life on Faux's kernel. When I switched to stock I was getting 18 hours
This is my battery from when I woke up until now, about 10 hours so far.
Light usage so far, just while I was at work. Screen was on for an hour.
I'm very happy with my battery life, if I leave the screen off I barely lose any battery not even 1% an hour.

so what was the problem? I saw a huge improvement with faux on stock debloated rom, easily getting a day out of it and sometimes 2+ days with light use.

SGA Battery Life

Ok I know the galaxy ace's battery life is suckish but just how suckish? What's the longest length of time your ace has lasted? And what rom are you using?
PS Does using your phone while charging have any effect? Cuz I've been doing that a lot
oh my god, my battery is damned. it only last for 2-3 hours if used used for browsing. i used RC vo-1 miracle edition, and im bout to change to another custom rom. any good idea?
When u use your phone while charging I think the battery life takes a toll ..
Well mine lasts 6 hrs on net CONTINUOUSLY ( yes sometimes I m online for 6 straight hours )
When I don't use it much it lasts for a day and a half ....
What are your stats? ?

Haha no actually I went to camp and they confiscated the phones and I forgot to turn it off. According to the stats, halfway through it got turned off (maybe they got tired of hearing the happy and you know it ringtone). So after 2 days and 4 hours of batt use, it was 53% and I just used it all the way home so it drained in a few hours.
mine last for a day and 9 hrs with heavy usage of texting and 2hrs of wifi and 3hrs of music playing
Mine lasts about a day with medium to heavy usage.
Just incase, I have two spare batteries.
Use a stock based ROM and it could last for two days.
-Disable background sync for inet app.
-use tasker or juice defender to schedulle wlan/3g connection.
-use sla battery 7amp for main battery
-use pc for games
-set phone on flight mode

its two different thing comparing symbian and android. symbian already known for power efficiency while android as power hogger.
moreover ace battery life is worse of all i've ever seen. i own a se live walkman, while its battery is 1200mah, lower than ace, it can last twice as longer than ace while still being oc at 1.4ghz. ace while got 1350mah and just stock 800mhz is crap, couldnt last a day without recharge.

ARMv6 vs ARMv7 much ?
Defy-ing all limits.
I find using SetCPU to do wonders for my battery life. You do need to root your phone though.
around 3 hours heavy wifi usage
medium to heavy texting half a day
playing games only about 1 and 1/2 hours
using super sedan class
In my opinion, with medium usage of SGA you got to get used to charging the phone every night, otherwise your phone might just shut down in middle of 2nd day.

So is i717 just flat out a battery killing device with no hope?

The phone awesome but you'd think with a large battery. ..battery life would be stellar! !
It sucks on stock and unofficial Rom.

Not sure what your doing but maybe your battery maybe not holding a charge like it should?
Eric
Do not use Hyperion, QCell or any other cheap ebay/amazon batteries. They are only about 1700mah at best and will kill your phone under moderate use in about 60 to 90 minutes. Maybe less.
I'm on stock GB rooted with all bloat frozen via TB and I can get through a whole day of use on one Samsung OEM batt with light to med usage.

This is no where near the average!
And you seriously must not use your phone, like at all
17 hours at 73% is a bit extreme, but so is 2% per minute drain.
I think I can represent a fairly average user. I usually check email, weather and a little reddit during my morning routine. BT is always on and connects to my car while I drive to work for about 30 minutes. I average about 2 or 3 long phone calls a day on my phone. Some text messaging throughout the day and some short internet sessions on my phone while at work. Plus a few minutes here or there for Draw Something. I stream Google Music every day on my way home for about 30 minutes. Once at home my usage varies depending on what I do for the evening. But so far I usually find I have about 50% battery life when going to bed. I actually made it through Friday and Saturday on a single charge.
So I would say that this phone has above average battery life for an android device. It isn't stellar, but it isn't bad either. My Infuse could eek out about the same life with less use. My N1 never made it even close to this length. My buddy's MyTouch 4g can't usually make it a full 24 hours.

Considering the screen size, the battery isn't actually that big. It sounds enormous due to other phones with almost a thousand less mAH, but I just bought a bunch of extra batteries. The removable battery feature is the biggest reason I switched to Android.
LTE is a HUGE battery killer. I turned off wireless since LTE is SOOOOOO much faster than any wireless connection I'm on. I'd be lucky if I could get through a workday without it being below 50% by the end of a work day and completely dead by 7pm.
Turn on wireless and it's now almost 3pm and still have 78% left.
Lets face one fact everyone is different. .everyone claims this and that and regardless of what carrier or what device people will.never see the batt life they would really.like to see.Say like 50% after 3 days heavy usage that would be a thing we.may see in.smartphones in a few years. Android o.s will always be battery harsh.Its a huge topic.
Another point.on all the claims of Great and terrible batt life has to do with the fact. .people just dont truly get how others may use there devices so heavily..streaming vid...music...downloads...mail sync...Some maybe few truly use there phones 24 hrs non stop. There probably will never be a batt drain solution for those people.So telling one person that batt is fine with all this moderate usage coming from a person who uses there data more like "lightly" rather than heavy, doesnt help a person who is a heavy heavy data user.Neither sides will ever come to an agreement.

best thing to do... use setcpu or some other overclock program. make a profile so that when your phone is sleeping it runs at the very minimum. my battery can last me up to two days depending on use. heavy use at the very least 7 hours

Wow that is awesome! I'm getting home with a full days use at around 50-60%- It seems to be better than my captivate was on life that's for sure.
I have had mine for two weeks- On side note? hehehe Does cycling a battery really prove to get better life as time goes by or is it a old school story about batteries use to have memory etc... and now they don't?
Modern batteries don't have memory but their battery meters can become decalibrated which can be fixed with a full change cycle. Nonetheless, I don't recommend doing that too often (I only do it like once a year) since that's bad for the battery.

Galaxy S2 bad battery life on every rom (even stock)

Hi,
I've been flashing roms onto my phone for months now and what I've realised is that the battery life is always awful. I hardly ever get past 10 hours, with just 1 hour of screen on time as my battery drains in stand by. I've tried cm7, cm9, perfect galaxy, miui, stock and many more, but my battery life always seems to be the same. Currently I'm running cmiui (latest version) and still battery is draining very fast. I read about people having amazing battery life on a daily basis.
My current battery life drains by 1% every 2-3 minutes of screen on time and about 5% of drain when in deep sleep or stand by an hour, sometimes even more. I use betterbatterystats, cpuspy and gsapp to monitor my battery but nothing suspicious occurs. Usually my 'awake' time tends to be 50% higher than my screen on time according to betterbatterystats, however all the wake locks tend to be kernel related. Changing kernel doesn't change this either. I've literally tried everything, installing several kernels, modems and calibrating my battery every time I flash a new rom.
Also what I realised is that my phone frequently overheats near the camera and even sometimes reaches 50°c.
I would appreciate it if anyone could help me on this topic. It is really frustrating that I cannot get through a day of even light use of my phone, which makes it almost unusable as I'm always concerned about my battery. I've also tried several batteries, so the problem doesn't lie with the battery.

I read about people having amazing battery life on a daily basis.
My current battery life drains by 1% every 2-3 minutes of screen on time and about 5% of drain when in deep sleep or stand by an hour, sometimes even more. I use betterbatterystats, cpuspy and gsapp to monitor my battery but nothing suspicious occurs. Usually my 'awake' time tends to be 50% higher than my screen on time according to betterbatterystats, however all the wake locks tend to be kernel related. Changing kernel doesn't change this either. I've literally tried everything, installing several kernels, modems and calibrating my battery every time I flash a new rom.
Also what I realised is that my phone frequently overheats near the camera and even sometimes reaches 50°c.
I would appreciate it if anyone could help me on this topic. It is really frustrating that I cannot get through a day of even light use of my phone, which makes it almost unusable as I'm always concerned about my battery. I've also tried several batteries, so the problem doesn't lie with the battery.

Everytime you install a new Rom/Kernel you have to wait for it to settle down (About 2 Charging cycles). If I flash a new Rom to my device Batterydrain is very high too at the beginning. What you can do is install a Rom and a kernel which supports undervolting and underclocking.
I use Resurrection Remix ICS 2.6.1 with the Siyah 3.5.2 Kernel with this Voltage/Clock settings (LESS AGGRESSIVE UV VALUES with -50mv and not -75mv undervolting):

With this settings I get 16 - 18 hours easily and with about 2 1/2 -3 1/2 hours of screentime and also about over 4 hours of listening music and doing other stuff of course.
Everytime you undervolt/underclock make a Nandroid backup!
Thanks, I've heard about the battery charging cycle before, I'm new to cmiui, flashed it yesterday but I've had cm9 on for about two months and the battery life was horrendous. I will try the undervolting and see how that goes

Strange, I am on stock and can make almost whole day with 3-4h screen time. Sounds like some issue either with battery or with the phone.

get a 2000 mha battery over ebay
I have been used 2000mah battery, miui 2.8.3 + siyah 4.0.1 kernel, no serious battery life issue :good:
I have a 1800mah battery, its actually not that much better than the stock battery, but doesn't the 2000mah add extra thickness?

Yes it does.

Yes but it`s no thicker than your speaker part of the phone.
I'll have a look at it, I've re calibrated my battery this morning and ismt half bad so far. Its 9 o clock now and sill have 38% left with about 1.5h of screen on time, phones been unplugged for about 10 hours. I've used the undervolt setting as suggested but still loose about 4% of battery in stand by each hour. On comparison my mums iPhone 3gs looses about 1% every 3 hours. Surely the android battery isn't that much worse

If it occurs with every rom you have could it be app related, wiggets or syncing too frequently?

That's what I thought but I've analysed my apps with betterbatterystats and gsapp, nothing suspicious came up and wakelocks are always kernel related. I've tried several kernels as well

Get cpu spy from the play store to see if your device is deep sleeping. Also, you can try 1900mah anker battery. I got two and a charger off eBay for $25 can. Definitely a good deal

Mysterious indeed, all I can suggest is what I would try which is to give a custom rom call slim rom a go after full wipes and format system. Its a stripped down rom and always gives good battery life as it's so lean. Hope you find a fix soon all the best.

maybe your battery is bad i bought a great 2500mah battery on ebay http://www.ebay.com/itm/2500mAh-Ext...ccessories&hash=item4ab6494de0#ht_2481wt_1163
that combined with the rom OLLO MONSTER gives me awesome battery life
I might have to invest in a new battery. As I said before I've upgraded to a 1800mah battery and using that but the difference is minimal. Also I have CPU spy and it goes into deep sleep quite a bit, awake time however according to betterbatteystats tends to be about 30-40% higher than screen on time. And i'll try the suggested rom after I've given this one a few more days on the undervolting

For BBS, anything over 1% is something that needs to be fixed. Keep in mind you need a good sample time (like over 5hrs)

Hmm looks normal, I would get the 2000 mah Samsung Original Battery because 10 hours and already on 38% battery is not so good in my opinion.

I've taken a few screenshots of bbs, somehow the kernel wake lock is completely empty which is odd
Also I only need the battery to last about 15h with 3-4h of screen on time to get me through the day!

Well that looks decent. Do you have key press sounds and lock screen sounds off? that could cause audioout_1 wakelocks
