I had problems with my battery, but since I rooted the phone I think that it is getting worse. I am not sure if it is the rooting, but now I am getting Android OS at 52% and the battery barely makes 5 hours. I am a using the phone, but it should last at least 10 hours. I did root the phone in order to delete batterystats.bin but this did not help at all. I used Battery Calibrator, also deleted the batterystats.bin from the Android Terminal followed the procedures of charging the phone to 100% waited until it says full calibrated the battery or delete the batterystats.bin discharge the battery until the phone dies and charged it to 100% again....but still the same thing. I guess the Android OS is killing it. Any suggestions will be greatly appreciated. Thank to all of you in advance!
52% is high, but that also depends on what other tasks you are doing at the same time.
You should have 5 hours of Screen On time if not more, thats what you need to check, not some hours.

5 Hours screen on time? I'd love to get that lol. 3 Hours 50 Minutes is about the best i've got, but then that is while battering the net and the camera.
Get around 1 to 2 days battery life though although I am a light-medium user.
Install the free version of Wachdog , and see if it can identify what apps or processes are eating up your battery.

So to make it clear. My battery lasts about 5 hours. I do not think this is screen time. This is the total time of the battery. I have at battery use
Android OS 52%
Display 13%
Android System 10%
Email 9%
Cell Standby 4%
Voice Calls 4%
Phone Idle 3%
Maps 2%
I think before the rooting I had Android at around 12-13% and the highest was the display. I keep the display close to maximum brightness, but it counts only for 13% at the moment and it was around 40% before rooting. Do you think resetting the phone could solve the problem?

I will again, and post the reading. Is there anything particular that I have to watch?
That stat you have given is after how many hours of usage?
Besides, what kernel did you use for rooting?
Install 'Better Battery Stats' and see whats going on in background.
And do turn off Wifi, GPS, 3G, Packet Data, Auto sync, Background Data, any running widgets when you don't need them. And also check if you have push-pull Exchange.

I got CF-Root SGS2_XX_OXA_KG5-v4.1-CWM4.zip I have after rooting Kernel 2.6.35.7-I9100XXKG5-CL420550 [email protected] #2. I think it was absolutly the same before rooting
On the battery usage it says 13H 23M but It was overnight and now I am charging the phone. Overnight the battery went down around 50-55% without usage. Yes I have WiFi and Bluetooth on all the time, and I am using 3G all the time when I am out of the house. Also I have a lot of auto sync and exchange, but because of this I bought this phone. I will get this app and see the results. With Watchdog Lite I get

Turn off wifi. You router is obviously one of the ones that are not compatible with SGS2.

I have Belkin N750 DB, and It was OK before. When I turn off wifi and restart the phone Android OS is still at 52%. Also I have no problem with my Galaxy Tab 10.1 on the same router. But thank you very much for the suggestion.
If you have wifi and bluetooth on constantly also 3g , you are really taxing the battery 5-6 hours is about right.

I am keeping the bluetooth on so it can connect to my car hands free. I will turn off the wifi and I will try to see what I will get.
I had simillar problems. High os usage and short battery life.
Used better battery stats overnight with everything data related turned off and fully charged phone. turned out that my facebook app was keeping the phone awake in standby and killing the battery. Lost 55% in 6 hours. Removed fb app and battery life is mutch better. Went from 8 hours with about 1 and half hours screen time to 14 to 16 hours with 3 to 4 hours of screen time on one charge. Os usage is now between 20 and 35%. Use to be at 50 to 60%.
This is with stock kernel with wifi and 3g allways on with some autosync and push mail allways on.

You just need to tap on Display under battery usage graph in settings.
Also FB doesn't stay awake in background if you Exit it. So think before you remove it, if it's needed to be removed or not.

Where you check your battery usage you can select the various entrys to see a detail summary and see what they did.

Since the phone was charged it is 1H 32M 16S. I am at 88% of the battery and 9m 3s on Display time. I do not have the bluetooth on, the gps is off Facebook app is removed. The only think that I gained is instead of Android OS at 52% I have it now at 48%
I rooted with KG5. If I try to root with KG6 do you think this might solve the problem? My stock was KG5 on a phone from Expansys USA Polish model.

Change britness to 20-30%, keep autosync to minimum, use juice defender. After flashing u should've calibrated the battery.my battery is great for my ussage of my phone.it lasts 18-22 hours with data on all the time , talked 1-3 hours per day , music 30 min per day and browsing on the internet when i'm borred.

If you keep juice defender installed in theory your data is not on all time.
I never got over 8 - 10 hours with 3g on all time, however I keep my brightness around 50-60%.
With green power premium and data on every 15 mins for 2 mins I get around 18-20 hours of usage but usually with more stand by than using the phone.
If I were to uninstall mail sync, what's up, facebook etc etc maybe I can get a lot more out of the phone but what's the point to pay for a data connection if you can't use it?
True. I have a job with a lot of spare time so...... i use the phone a lot.i like juice defender because when i lock the screen it kills data and checks from time to time all the stuff that needs data

From what i learned the calibration means after flashing let it drain until the phone closes then charge it to 100% unplug and delete batterystats.bin

For those of u with bad battery life and notice battery drain even while not using the phone juice defender really works wonders on the s3. It has literally doubled my battery life. I easily get through more than a day now an it just feels more like this is how the battery is suppose to be behave. The down side being ur data isn't always switched on when ur phone is in satndby

I found juice defender in the past to be a battery problem instead of a solution.
what's your battery now? how much juice do you get?
I think that anyone who experiences bad battery life should exchange their phone or battery. I can go two days without recharging and still have 29 % left. That 29 % might even last me through the 3rd day but I would prefer not to risk it.
I did a little test today.
I unplugged the phone at 7am when i got up.
I only turned it on for a couple of seconds, twice, to check battery level, and it had gone down to 75% by 9am. (so by 9am, no more than 1 minute max screen-on time)
Is that worse that others?
My battery does (like everyone else's) immediately drop to 99% on unplugging it - actually, sometimes 98% right away.
I'm surprised anyone gets more than a day's worth out of it?
I also noticed, when it was on my desk, that the screen switches on, on it's own every now & then. Maybe every half hour or so?
Is that also normal?
I'm having a bit of trouble with my battery aswell. I only have 54% left with only 1h15 screen on time and that was only for some texting and browsing.
Is this normal or should I go back to he store to check the battery?
Also, should I try the free version of Juice Defender or is it not worth to use it unless you have the paid version?

Dropping 25% in 2 hours time with a display on time of 1 minute is definitely much more drain than normal. My phone usually drops around 2-3% per hour if it's unused on my desk.
I also find it weird that your display switches on every now and then by itself.
You have a lot of apps that poll the net for data in the background? (facebook, twitter and so on)
Are you on wifi when this happens, or mobile data?
Try turning off sync altogether some day and see how much it drains your battery per hour.
Hi all ,
Today is my 1st day with new s3 bought yest. night and coming from s2,
My s3 was full charged this morning, and after abt 12 hrs of normal use ( some calls + facebook + whatsapp + viber . . . . . ) battery level is 60%.
I think that by this way new s3 battery will stay normally 2 days . . .
If people are experiencing high battery usage its because of your apps. All battery saving apps do is turn off your data or tweak your syncing.
On wi-fi with no much syncing, you should get about 1-2% drain per hour. On mobile date this goes up to about 2-4% per hour.
Tips for battery save.
- Switch off Google Back up & restore
- Accounts and sync, switch off what you don't need
- Email exchange accounts can be set with a "off-peak syncing"
- Be thorough with news and local based apps. Turn off auto syncing or reduce the frequency in which they sync.
- A good way to check which apps are using data when idle is by going into settings > Data usage. When you click on any of the apps listed, it will show how much data is used in fore/back ground. The ones with high background usage you might want to investigate. You can also disable the app from using data in he background by setting yourself a data limit
- Apps like Facebook, Google+ are battery hogs. So if you don't need it, uninstall.
My battery is awesome so far. 2 days with normal use and 3.5-4 days of light use...
Why does the a battery need to last two days? Can't you charge it over night?

It really depends on your usage. Screen on time tells something, but not everything. For example watching a hd-video eats far less battery than surfing on the internet with 3g. But still, the battery life is great, so no disagreement there.
My battery so far so good
Standard, not too heavy, day by day usage
One thing not mentioned so far is wi-fi. If you are connecting to a 'dodgy' router, this is going to eat into battery life. So if you aren't using it, switch it off.

Hi,
hope this question wasn't asked already, I searched for it and found nothing, anyway.
So, I'd like to know, when you're using your phone normally (browsing, texting), how many minutes does it take for 1% to drop? of course, I mean while screen is on.
I would appreciate if you also wrote which rom and kernel you're using. Also, what governor is being used, whether sync, Google now And location are on.
I'm currently using Slim + Semaphore (always switching governors), sync, GN, location and WIFI and under those conditions, 1% drops after 2-3 minutes.
Many people report hanging a great battery life, with 4-6 SOT and I just don't understand how it's possible. For comparison, I'm currently on 44% with 1 hour and 18 minutes SOT.
Please no flaming and such, I really want others to contribute to this discussion rather than hear something like "RMA your phone" and such.
Thank you.

It depends how you use your phone. I don't use facebook, i dont sync twitter or g+. I rarely use location services. The only things cause wake locks are whatsapp and hangouts for me. Then, I get 20 hours with 4 hours sot on wifi 2.5 to 3 hour on 3g. If i don't play any games i can get 5 to 6 hours sot (i don't know what can i do for 5 hours without playing games). It's not important in how many minutes 1% drain occurs. Sometimes 2% drain in 2 minutes sometimes no drain in 10 minutes. If you minimize your idle drain for your usage like get rid of unnecessary apps and greenify the apps have unnecessary notifications you can have 4 hours sot with browsing, twitter, xda, messaging and playing not heavy games.
I use latest nightlies of pa and franco all the time.

I have very poor Battery Life on my new phone. Last night I factory reset the phone and at 11pm I fully charged the phone and left it in airplane mode. This morning it reported 58% by 7am this morning.
It's much worse in daytime light usage. It's flat after about 4hours.
I have noticed that the WiFi and AWAKE history graphs in battery section show WiFi always on and phone is always awake. Even when the WiFi is switched off it is always ON according to the graph. The phone is constantly warm all the time. I have contacted the UK supplier. Awaiting response.

I see no such option on the Axon 7.
This probably depends on phone manufacturer, try find menu or more in Wi-Fi options, most of Android 4/5 usually have this option, sorry I'm only potential buyer of A7
---------- Post added at 14:18 ---------- Previous post was at 13:56 ----------
Sorry, ZTE Axon 7 doesn't have option "Scanning always available"(User Manual page 57), Older ZTE Axon it has (User Manual page 53).
There is an option to turn Wi-Fi off when asleep in the Wi-Fi advanced options menu. Might be worth trying.

Sounds like this is a settings issue, not zte or the phone.
This battery drain is obviously the result of a wakelock. Adjusting WiFi settings will not solve your problem.
Have you checked the 'fast battery drain apps' in power manager. Mines not liking Amazon music and the Android central app.

Download the Battery Monitor Widget App. It can monitor everything about your battery very accurately. Even your SOT stats.
Fully charged up my UK axon 7 phone this morning. I powered it up at 7.35am it was totally flat by 12midday. I had factory reset phone and not installed any apps. I only had data switched on via sim. GPS, WiFi and low power mode on. Used it very sparingly and it went flat.

I think that is an issue, however I am still not getting the battery life reviews have been getting....
The first few reviews talked about amazing battery life with SOT of 6+ hrs on this phone but in my opinion it is worse than the OnePlus 3 I used for a few days. Yesterday I got just under 4 hrs of screen on time, taking my phone off the charger at 6:30am and plugging it in at 11pm with about 4% battery left. I am using GSAM Battery Monitor and Phone Radio is taking a solid 37% of my battery, is that normal? The phone does show it has a weaker signal than any of my last phones in all familiar locations but I haven't actually noticed a difference in internet speed (actually getting 40mb pretty regularly) or call quality/reception. Today I am at 63% battery with the phone being unplugged 10 hrs 47 min and only 1hr and 16 minutes of SOT. No apps stand out as using a lot of the battery with App Usage being at 1%.

What those 6+ hrs SOT stories don't tell you is that they gimp the phone ie turn off most if not all background processes such as: location, push emails, anything that has a hook to the web.
I mean I can always get 5+hour turning off all my smartphone services and just having my screen on to flipping around looking at locally stored stuff.
An average best for me is usually going to bed with 4+ hrs of SOT by midnight. @15% remaining and that was before the wake lock I mentioned above.

How is 4 hours horrible? 4 to 5 hours is really good battery and is a standard for any flagship device.
I don't get people that want 6 hours of screen time. Don't y'all have anything to do through the day? Spending 6 hours a day staring at a screen cant be good for anyone.

I guess I got spoiled with battery life on my old Huawei mate 8 and other phones with amazing battery.
I've been getting over 5 hours SOT pretty consistently for the past week. The battery life is way more consistent than my Nexus 6p was, and seems to last noticeably longer. I also don't worry about topping up when I get home from work if I really need to (or if I watch YouTube for 3 hours after I get home) because of how fast it charges, even if you use while charging. I'm very pleased with battery life overall.
