Battery

Ok... What are all of you doing for your battery life? I just watched that video from the guy who showed the SetCPU and stuff and don't believe his battery is that good. My phone has been off the charger for 20 minutes and Klaxon was running and it is down 5% already AND I have the 1600 mAh Seidio battery. It just isn't possible. Android is a battery hog. I've messed with SetCPU and noticed nothing different. I have the sleep profile set to like 245/3xx and I messed with the advanced settings. What do you guys have your advanced settings at? I have the screen brightness on auto and I don't use twitter/facebook/news. The only data all day is my Touchdown e-mail and weather updates as far as automatic goes. Can someone please shed some darn light here? For the whole day at work I have full 3G and Bluetooth is on, but no WiFi. Any help, PLEASE?

Do you get good reception at work? Bad reception wastes battery life.
Have you tried running the phone down to a low 5-10%, wiped battery stats in amon's recovery, powered off, and given a full charge to help reset it? This can help.
You dont have that notification in succession stuff going that keeps you in a wake lock state right?

Seconding the recommendation to wipe the battery stats.

How do I change notification in succession? I'm on the latest Cyanogen which I believe included that. Also, how do I install the UV .33 Kernel - will that help? And where is the amon's recovery to wipe stats?
Thanks for all of the help!
EDIT: From Modaco's kitchen, I did Cyanogen - so is that the kernel I want. And nvm, I do know where the wipe battery stats is. Brain fart. So I should leave it charing while off?

Check this out - are we sure Klaxon isn't doing any damage? Or is there anything else of concern here.

I got the two extra batteries and external charger for $20 bucks from China off ebay. They work phenomenally. I haven't ruled out the possibility that they are giving me some kind of terminal illness though.

What was the benefit of the external charger, battery last longer? if so much better than before?

welp. When the current battery cruds out, I pop a fresh one in, and then the empty one goes into the external charger.
I got the extra batteries originally for long trips etc, but this current system seems to be working fantastic.

Man what do you recommend to make your battery last LONG..

After I installed setcpu, my phone is getting an additional 1/2 day of life...so something must be eating your battery!

2 - one Seidio 1600 and one stock 1400. I just threw the stock one in and will wipe Battery Stats as soon as it hits 100% and then see how it goes tomorrow. Should I be using SetCPU or no since I am on the .7 Kernel?

I never rooted so couldn't recommend what to do. But if you know its not tested then don't. Use a supported kernal always to minimize your problems and headaches..

I haven't rooted yet. I did the turn off notifications thing and get a sms program from the market thing. worked wonders.

setCPU profile to screen off max power is 245, UV kernel, I get around 50 hours use.

My Battery Life WOW! *Pic for Proof*

Using Myn's ROM with the Battery Tweak, I have FaceBook syncing and I have 2 gmail accounts syncing along with Weather every 3 hours, Facebook every 2 hours.

Not needed. From the pic he attached it's obvious the phone was in standby most of the time.

Man, you even use ya phone?
What is with this obsession of battery life goin on 'round here? I say, as long as you can get better battery life than a stock rom, you've won. Keeping the phone on for a day or two without charging seems like a good idea, but everyday isn't the same, and one day you may need to use it way more than any other day..if you start that day off with only 30% just because you wanted to see how long your battery would last, then you really gotta limit how often you use your phone just so that it can make it till the next time your around a charger.

The battery needs to be charged? I bought my phone back in June. The battery is now at 70%. I figured I just had to buy a new one when this one runs out.

Barely used phone. Come on.

Display 4%? Is that possible?

I can go a full day and a half, 36 hours, without a charge and I am using the original sense android... and I use my phone normally, I text, read usatoday, tmz, check email a few times, use the xda app... and I have wifi on all the time! What's this beef with battery life on these forums? Mine lasts forever! I just have things update manually, I don't let anything run without my permission.
I do, however, turn my phone off the 6 hours I am sleeping.

wifi is on = low battery usage, atleast in my experience.

Indeed. I got 1 day and 19 hours on stock nonrooted 2.2 back. and i used it for some medium texting. and some gps applications...maybe 2-3 hours max awake time. i dont think you used it much...the excessive 3G usage from FB doesnt mean anything.

You should be able to get what you're looking for from the Spare Parts app.

According to mine, it's 122 min of screen on usage.
I had this scenario on my phone running myn's rls2 + king cfs #11 yesterday:
since unplugged - 24 hours
display on - 1 hour 25 minutes
charge remaining - 50%.

so i wanted to find out how long the battery would last on standby, and to my surprise.. it turned out to be nearly 58 hrs!!! that was on stock sense rom. non-rooted. and of course with very very minimal use. i basically just left the phone alone on my desk or in my pocket all day.
here is the screenshot i took back in july:
but that kind of battery life is unrealistic with normal usage. I am a moderate user (on the higher side), and i typically put my evo on charge everyday in the morning when i get to work (on weekdays). so, the charge on my phone lasts about 25 hrs with normal usage, that usually means about 4-5hrs of Awake Time. this is after rooting the phone. and i am using a stock rooted sense rom. i have had similar results before rooting the phone as well.
on weekends, i find myself charging the phone about 3 times (over 2 days), as the usage of the phone goes very very high.
i have a charger on my desk at work for the weekday charging, and a charger in my car for the weekends.
i have recently installed setCPU, and havent really seen that making too much of a difference, but that perhaps has to do with my usage pattern.
as pointed out in many a threads, signal strength is one major factor when it comes to battery drain. i live in Atlanta and i have great Sprint coverage where I am located, and that makes a world of difference.

it would help if you indicate the battery life that you were getting on stock or any other rom you were using prior to this. because there are so many variables that come into play as far as battery life is concerned. so that will help put your claim into some perspective

Battery drain by ANDROID OS

Battery drain by ANDROID OS
5hours 50% battery gone..
now using simply honey 3.3
how to fix it?
>.<

heard a lot abt battery drain in GB ROMS.. but i m on darkys v10rc6(2.3.3).. and i felt the battery was better than v9.5(i.e the 2.2.1 based rom)

last nite after a call..then i slept
wake up saw my fon battery gone >.<

any way to fix it?
is it the problem of TWEAKS and EXT MGR setting?

I tried Tweaky Rom after using Stock JVH and i like the whole Rom and lock screens and etc , but my battery wouldnt last more then 10 hours , flashed back to Stock JVH , rooted , flashed KC1 modem and getting 2 days easy with moderate use , on Tweaky it would drain about 15% every few hours , to bad as i like his ROM a lot
Hitec

u means TWEAKS and EXT4 will cause the problem?

Android OS battery drain issue is explained here.

although people argue wether it works or make sence the following sorted it out for me on dakry v10RC6:
using Titanium Backup
:delete data of
-Samsung Account
-Software Update
and freezing Software update
Afterwards I didn't face the drain agan I no negative sideeffect yet

thanks..
so my phone drained all battery also will solve the problem itself,lol..

just try to wipe batt stats from CWM make sure you full drained battery first and charged to 100% then go to cwm wipe batt stats remove charger and reboot.
**disclaimer some what related
as per codeworkx
Why my phone only charges to 94%/96%?
The Android OS wont ever let you actually charge to 100%, because charging it to 100% would wear-out the battery alot faster then charging it just under maximum.
On Sammy Roms it just usually tells you its at 100%, when its really at 94%/96%

get systempanel from market so you can get more details about exactly what process under the system is using the cpu.. but my guess is it is the std suspend bug in gingerbread... that is why i am still running froyo.

I did not found solution too, now I am staying away from gingerbread as far as it is possible.
I could add that my 4 month old micro sd kingston class 4 suddenly got 8 bad sectors maybe ginger was on it for too long...

jbdroid's link helped me alot on this issue. I'm running Tweaky's and almost did what Hitec did, because the rom would deplete the battery in 6-8 hours occasionally. Stock JVB would last 36 hours on average. So every once in a while I'll pull the battery, sd card and SIM wait a few minutes and re-boot. It's not much of a problem because I have a mix of batteries with different capacities (3500,3000 & 1950 mAh) and I charge them on external chargers exclusively. I also wiped the batt stats and calibrated. I installed a program called Autostart, which kills some services like updates and maps after start-up. Now I get about 20-24 hours use, not as good as stock JVB but acceptable enough to stay for a while on Tweaky's. And the speed is a good trade off over stock.

You are not worried about your nice phone slowly dying ?
Things you did have absolutely no impact on this HUGE GINGER BUG. On darkys 9.5 i have 72 hours standby or more that i have never recorded because of course some usage in the meantime always happens.

BIG battery problem

Hy everyone,
after i change rom to cyanogenmod7 my battery life is very bad. Here is what i did...
Rooted, installed CM7, battery was bad, restarted battery stats (i red it somwhere on this forum that whan changing rom battery stats have to be restarted), before that restart battery was, well not good as in stock froyo, but average... after that it is terrible. In just 6 and half houers when i was sleeping it was drained 33%, and after i wake up and use phone, in just 15min it loose 10%. When i looke at 'what use my batteru' cell standby is 45%!! Thats not normal, right? How to fix this isue?

It looks like you reset battery stats when you weren't on full battery.
Only reset when calibrating battery, and your battery is full.

It was full, than disconected from charger, than restarted battery stats, after that drained completly and charged to 100%.

Might have had a bad flash then, unless your battery is still setting in, give it a few cycles and it should start to give you better battery life

And don't keep the minimum cpu frequency value to high. Because the phone doesnt need a huge frequency in standby mode. That also matters.

I also recalibrated the battery and reverted back to stock froyo rom (with overclock kernel and I removed a bunch of system apps). Battery seems to last a lot longer now

Another solution would be a 3000mAh battery i saw somewhere.. phone gets a little bit thicker, but its perhaps worth it?

I will try that. What kernel did u use for that? And how did u remove system apps?
But must say, 23h 18m since of the charger and battery is 41% with some wifi/data, 12-30 sms and few cals. Still not good as FroYo, but not so bad as before recalibration.

For the first few runs after new ROM and batstatts try to have some full cycles

infinity mc4 kernel. you can remove system apps with Titanium backup (button backup/restore -> select app -> un-install). Look out that u don't remove apps that are active used by the ROM. I have deleted like 30 apps + widgets.
yesterday same time, like in my post above, from 99% to 97% with wifi/data on. So much better!!

I have the same battery draining problem since I flashed WildPuzzleRom and I think of going back to stock ROM...

Over the last month or so ive tried various roms nightly's etc and the most i got out of the battery was around 15 hours with the batt stats fix, froyo on the other hand different almost 36 hours at the best and worst still around 18.

Just found my old one dead

My battery life is strange. Once it can handle 6 days without charge(i put it charging at 15%) using wifi, alot of dialing. Second time it handle only two days without using it. Last time it handled 4 days with same dialing and wifi.
I am using Cyanogenmod 7, Smartass governor, min cpu=245mhz, max 710mhz.

[Official] battery stats thread

Once we get charged up (and back down), let's see how the battery life in the S4 compares to the quad core.
Please make sure to include your screen on time, as that is the best indicator of light/heavy use.

pleasantly surprised
I can't believe how good the battery has been so far, 84% after 13hours (over night)
I am a light user. still - that is impressive for stock. I never got close to that with my OG Epic on stock which was usually 3% per hour.

Not too bad for first day with moderate to heavy use!

This is heavy usage. Screen on time of 3.5 hours. Downloading Max Payne and a lot of apps. Downloading and listening to audio on Google chrome. Lots of Pulse usage. Games, YouTube, and 30 minutes of phone calls.

on mine its been at 7-9% and i dont know why, i have something waking up my phone when the screen is off and it might be that... ive forced stop, but i check later and its active again, ive disabled the service and the Allshare play in the application manager but still comes back on... hmmm i think im gonna have to root and just get rid of that file, or freeze it or something

Question... Does having all the motion settings on effect the battery? Also does having the NFC and sbeam on hurt the battery?

I wish I could get some stats like that. The screenshots are while I was sleeping and 7% seems like a lot of drain for it just sitting there. Only thing on was wifi. Cell standby time on is always the same as the time on battery, is that normal?
edit: the phone now shows 79% battery left with time on battery of 12h 46m; cell standby the exact same; screen on at 9% with time on of 48m. I'm fully stock and running power save mode.

Here are my stats. I think the battery life isn't too bad so far but we will see.

are the battery stats suppose to reset when you restart the phone? For dinner reason my persist even after a reboot

No, they will carry over until you re-charge or change the battery.
I was going to make a thread like this, but it was already here! Here are my results after my second full charge and regular usage. The results are on par with my fully modified and decked out Epic. Of course, this device has a bigger battery, but it also has a larger screen. Between the hardware and software upgrades, I'm very impressed with the stock battery life. This includes wifi on at all times as well as signal w/data. Some motion features are enabled, nfc is not, and google sync is off (I use stock email). Now how much further can this be improved?? Remember not to be discouraged, Screen On times will vary depending on what the phone is used for. Showing pictures is much less battery intensive than watching YouTube videos.
