[REF] - - - BATTERY Life Thread - - - Tips & Tricks

I do realize that everyone is probably going nuts playing with their new units and draining the battery life mad but I figured we start a thread to get general battery usage times from owners. We could also come up with a format that's acceptable, I'll start with this but we can change it as we go.

There is a battery saving mode that is included with the phone under Settings.
Because of the Super AMOLED display, darker colors use less power. Therefore:

Here are a couple of things that really helped my battery life:
Turn off TMobile's contact sync
- Menu -> Settings -> Accounts and sync -> uncheck T-Mobile Contacts
Ensure mobile data is not active when connected to WiFi
- Install Llama (https://market.android.com/details?id=com.kebab.Llama&feature=search_result) and launch it
- Add an event called WiFi
-- Add condition: WiFi Connected (any network)
-- Add action: WiFi Sleep Policy (never sleep)
-- Add action: Toggle Mobile Data (off)
- Add another event called WiFi Disconnected
-- Add condition: WiFi Disconnected (any network)
-- Add action: WiFi Sleep Policy (sleeps when screen turns off)
-- Add action: Toggle Mobile Data (on)

try SETCPU since you are rooted
make a profile for screenoff (i use 594-128)
that way when your phone sleeps the processor slows way down and doesnt use the battery as much
also if you meant when you sleep.....whenever you can.....use wi-fi and turn APN data off. That way the phone isnt searching for a cell tower constantly and using battery.
Hope this helps....PM questions

FOR 100% NO DRAIN ISSUE
ralnee said:
Okay.. I finally have some answers. I registered my phone on the Samsung site, and got into a live chat with a rep. I explained to the rep (as best as I could) that the battery usage was not updating once it reached 100%, without a reboot. After going back and forth (did you try A, yes I did, did you try B, yes I did...), she finally gave the the number of their "dedicated Galaxy S phones voice support team at 1-877-EZ2GALAXY (1-877-392-4252)".
I called the dedicated team and was finally told that this is a known HANDSET ISSUE, and to replace the phone.
I'm performing a full backup using Titanium Backup as I type this, then I'm going to do a NANDROID recovery (I think) and then reset the phone to factory settings. Then I'll replace the phone at the tmobile store I purchased it from.

LOL this has become a standard in almost every device forum now, there must always be a Battery Life topic somewhere
might as well make this one a sticky so EVERYONE please use only 1 topic to keep track of the battery life and tips & trick
and avoid making like 200+ topics of the same thing...
Thank you

I saw this earlier, might even have it installed, good find!

If I have time I'll try to set up a test for running with/without the Samsung battery saver mode to see if it really helps. I'm pretty curious

Does the SGS2 charge to 100%, unlike the Nexus S?

Sure, and actually any battery app widget will show the battery level. The Nexus S stops charging at about 96%, so when you would unlpug the charger after it says 'charged', it immediately drops to 95-96%. I ended up buying a couple extra OEM batteries and a wall charger for them so I could pop in 100% charged batteries. Plus it made it so I never have to waste time charging my phone. When the battery dies, I swap batteries. Since this is the same 'family' of phones, I am real curious if the SGS2 does this also? Someone please confirm. Thanks!

If someone doesn't get to it before me I'll confirm soon. I want to let this bad boy run down to zero before charging again because it's draining a little bit faster than what I want.

I've read about this too, I thought they adjusted it on the software side though (so 100% displayed wasn't really 100% but actually more like the 96-97% of the actual charge on the battery, hence the calibration. I might be wrong though.

It does charge to a full 100% and gives that familiar notification that the battery is fully charged and to unplug it. It drops right to 98% after a few minutes though. Haven't really paid much attention to it just this once.

I can confirm that I have seen this as well.

Can someone pull their battery cover and post the OEM battery p/n? If I get this phone, I will most definitely order some extra batteries and a wall charger. I get 2-4hrs more battery life in my Nexus S charging them to a full 100% in the wall charger and will likely have similar results with this phone. Thanks

Nexus 7 2013 not fully charging

I have had my N7 for a few days now (fully rooted using Buttered AOKP ROM and ElementalX 1.8 kernel). I have a US power adaptor with a UK adaptor. I have my N7 charging all night but it doesnt seem to go all the way to 100% - it gets to about 96%. Is this a known issue? Is it worth returning/exchanging the unit?
I bought it (£170!) new from play.com.

It's not a feature to extend the battery life of the device as in how many hours you can use it off the grid. It is a feature to extend the battery life as in how many charge cycles is the battery gonna last. It has been shown that if you drain a battery fully and recharge it to 100%, you put more strain on it than if you let it drain to 20% and charge it to 80%, that way you increase the usable charge cycles by a lot. That's what that feature is supposed to do.

My n7 has not been charging fully either. I am using the stock charger and I'm running PAC ROM for about 2 months but this just started happening. Idk why. This picture is after I had my tablet plugged in all night while charging

[Q] Battery life is so bad, it won't charge while in use

I am running BlueLightning-20140410-jflte as my ROM, with the 3.4.82-ChronicKermel-KK4.4-AOSP-JFLTE-v3.1 kernel.
I have my governor set to ondemand, with my low clock speed set to 189MHz and the highest at 918MHz.
With the sound set to one click past off, with Wifi, Mobile Data and GPS turned off, with the screen on the dimmest settings, my battery STILL drains when I have the phone plugged in, if I am actively using an app or playing a game.
I did not find a Fast Charge option on this ROM, and I had to uninstall Xposed Framework, because it was preventing several of my apps and games from running.
I can't think of a reason that the battery would still be draining this quickly, using the settings that I described.
Is there something I am doing wrong, or something I missed along the way somewhere?
Thanks in advance for any advice.

Try a different kernel

To what are you plugged while charging? If you are plugged to a wall-outlet, make sure you are using the Samsung wall adapter (or at least one that can push 1.9A). I've found out that it isn't usually the cable that causes slow charging, but the wall adapter.
Also, download an app from the Play Store called Charging Current Lite to see what your charging rate is. While 1900mA (1.9A) is optimal, anything above 600-700mA should be enough to charge while in use. Much lower than that, you will only maintain what charge level you have or slowly drain power.

It's usually the wall adapter, but it is not the one that came with my phone. I got mine off of Craigslist, and it didn't come with a charger. I've been using the same one I used on my old LG Optimus L9. I never considered that.
Figured that plugging it directly into my computer via USB would give a weaker charge, but never thought it could be the wall charger, itself.
I'll run those tests and report back. Thanks!

Charging via USB will put you in the range of around 480mA. Even with fast charge on, it's somewhere around 600-700mA.

Phone doens't go into Deep Sleep while connected to Charger

Don't if anyone has ever noticed this but, the phone when charging or connected to charger never goes into deep sleep. CPU stays at 300mhz all the time.
Don't know if this is normal, or a normal android thing and actually doesn't make any difference since it's charging...more just a a curiosity of mine !!!
Cheers.

Same here is there any fix because no other phone I've had has done this

This is normal.

My phone is warm when charging. I don't expect it to be cool to the touch when its charging at 2 amps. Thats Ipad status current flowing in the battery and the device. ?

Charge time

Am I the only one who has slow charging? 1 hr on airplane mode and it went from 17-30%?

mine definitely charging faster than that. didn't really measure but very sure it's about 2 hour for me to get from 5% to about full charge. original charger with mobile data turned on.

yeah , calculate accurate and post it :good:

Mine went from 6% to 62% in 59 minutes today. It reached 100% after about 100 mins. Stock charger and stock cable. You have to look for the double lightning bolt symbol in the battery icon to know that it's charging rapidly. The fast charging only works with the stock charger. I tried charging with my Nexus 6P charger which charges that phone quickly but didn't charge my Honor quickly.

The company has made a claim that it takes 1 hr 50 min to completely charge with their OEM Charger. So I am sure that the QC3 works fine since the battery capacity is also 4000mah. Other phones with 3000-3300mah charge within 1 hr 30mins coz they have substantially lesser capacity.

just sharing the stats from last night:
22:51 @ 5%
23:02 @ 13% (11mins; +8%)
23:42 @ 50% ( 51mins; + 45%) // (40mins; +37%)
it does look like we can get about 100% in 2 hours.
and sorry, didn't continue with measurements coz i was already zzZZZzzZZz... tiring day.

Next time if you experience slow charging you can try flipping the cable 180 degrees and try. Because that's what I've noted and even @venugopalu007 also experienced similar thing.

I use Ampere from the playstore to test the voltage on all my phones, so I can figure out what connections work best.

I am also noticing the same thing. This is weird.

Mine can definitely go full charge under 2 hours charging from about 10%, BUT only if I don't touch it at all. If I use the phone at all during charging it charges at a literal snail's pace even if I open low power app like an ebook reader. Screen is always set to around 35% brightness, and I'm using stock in the box huawei charger. Ampere gives it a reading of 1060mA then it goes down to 600ish mA and it does display the doublebolt in the battery icon . Is that normal? At times it can charge for 40minutes while I'm using a game app and it barely increased 1%(screen on) While my sister using a micro USB charger on her xiaomi redmi note 4, had no severe slow down on charging times even when playing intensive games while connected to the charger( Same battery size I believe).
