Hello this is my first xperia smartphone. I'm impressed about the battery of z2 but I have question about battery life, I have auto brightness auto, Sleep 30 seconds, mobile data on, nfc off, Wifi Always on, stamina mode off. I looked into may battery usage and the screen usage is using 62 percent? When you charge your z2 phone is it necessary to make the battery turn to 0 percent before charging? Mine was I discharged it to 0 before charging it but when I read about the battery Li-Ion that it doesn't need to be discharged to 0 is this ture? .How to make the battery life of z2 last longer but not damaging the battery itself? Any tips? Thank you!
You shouldn't discharge your battery to 0%, never! Personally i never discharge my phone under 10%, when it is 14-15% i plug in the chager.
It's bad for your battery life to discharge it to 0%.

So I think I damaged the battery of my phone. After I read about that Li-Ion battery I never discharged my phone to 0. I have bad experience about my HTC One M7 I always discharged it to 0 and now when I fully charged the htc one m7 to 100 percent it will drastically go down to 92 percent after 5 mins.
Might be, so never discharge your Z2 to 0%. 10% should be the lowest.

Thanks buddy! But the screen usage of the z2 is eating the battery of 62 percent :crying:
I don't think so you damaged battery discharging battery to 0% once, moreover it was "user 0%", battery had some energy inside. So keep in mind that optimal for battery is work between 40 and 80% but of course it is not very convenient.

Wait.. obviously "Screen" usage takes up the most percentage on a phone because you're using it? Judge the battery overall when you reach from 100% to 15% or so.
I'm pretty sure you have no idea regarding the battery usage, you should take your time to read and understand it. :good:
60% used by screen is good, that means there aren't any apps in the background eating your battery

It is normal. The screen takes a lot of the battery. My SOT is between 60-70% battery drained.

Is it necessary to calibrate after flashing a new kernel?
Not really. I found my battery life is better after I flashed the new voodoo kernel by jt. If you do have some bad battery life, it would be suggested you do calibrate your battery.
how do you calibrate your battery also i notice after i charge my battery all nite the next morning i start off with either 99 or 98 percent any reason why???
Calibration of the battery isn't really required if you flash at 100% each time.

This is expected behavior designed to protect the life of your battery. basically what happens is your phone will charge to 100%. It's not good for a li-on battery to stay at that stress level so the phone will then allow the battery to discharge to 95%. Once it hits 95% you will start charging back up to 100% and the process will repeat. If the phone didn't do this the battery would degrade much more rapidly.

thank you some days its good and some days its bad........
,this is how i calibrate my battery,before i have 45min of standby it will decrease from 100% to 99% but now it is 2hours & 34min before it go from 100% to 99%,i felt the drain after 2 weeks of overusing my phone (1week playing paladog and 1 week flashing different roms,kernels and theming my phone with different launchers),
- Charge your phone to 100% while it’s on.
- Unplug it from the charger, power off, then charge for 15 minutes with it in a powered off state.
- Unplug charger from phone. Power it on, and then charge 15 minutes while the phone is on.
- Calibrate battery using battery calibration by NéMa then unplug charger reboot.
- Power on, charge for 15 minutes then unplug.
- Finished.
note: deleting battery stats(calibrating) don't increase your batterylife said by others and it is just a placeboo and i believe in them,but it fix my battery drain so why don't we give it a try,there is nothing to lose,battery drain is so annoying.
,thanks to NéMa for the awesome apps,
,thanks to jgezau for his thread as my reference,

That was from LEWA OS, one of the best rom at that time...:good:
First and foremost, a Google engineer debunked the idea that batterystats.bin has anything to do with how the phone charges. By deleting it, you're actually inconveniencing yourself, as there will be a short period in which you won't have accurate stats.
Secondly, the O1 has a lithium ion battery. Lithium ion and lithium polymer batteries don't need to be calibrated, as they have no "memory" effect (you can read more on that here).
Moreover, these batteries have built in charge circuits that protect and regulate the battery. Ever wonder how the phone knows the battery temperature? It's pulling it off the charge circuit. That same circuit also prevents the battery from ever being overcharged or discharged fully, which is why that convoluted guide about calibrating your battery by draining it to "empty" and then recharging it to full doesn't work. Worse yet, intentionally draining your battery is actually counter-intuitive, as lithium-based cells wear more as their percentage of discharge increases (you'd be hurting the battery in your effort to calibrate it).
Your instructions aren't detrimental, so if it works for you, go for it. However, based on my understanding of these batteries, it seems to me that this procedure is inconsequential.
Besides, a new battery for the O1 is only $6 USD on Amazon or Ebay.
Guys, kindly help me, I'm not quite sure on how to properly take care of my Xperia P's battery. Should I discharge it to 1% and charge it to 100% all the time? or should I charge it often?
There is no problem in charging often but atleast you should let it drain it upto 50 to 60 percent

Its a myth - you don't have to drain your battery completely and then charge it again to the fullest for longevity
leap before you think

Thank you for the quick responses guys
Both of us, you and I have a lithium polymer battery. Some tips I follow for the life of my battery pack.
1. Do not let battery discharge to less than 10% too long.
2. Always charge your battery short of 100% ie 85-95%
3. Always turn off your phone and charge the battery to get an accurate reading of battery percentage.
Cheers....

Hey everyone
I am having a problem with my battery drain.A few days back my battery was fine i am using lg LTE 2 phone with a 2150 mAh battery.

As you are saying that your mobile seems "hot"
First you need to confirm that its charger/device issue or only with battery.
First do battery calibration with this method: (In this method you need custom recovery for your device
This may help you

Dont forget to thank him there on his thread.
IMPORTANT: You can skip this step>> "Wait 20 min after you are sure it is 100% (phone should stay plugged in)" - As i dont know much about LG devices and their batteries
Now some advice from me-
If you can cover it >>> Never charge battery again and again before 15 or 20%
Always charge your battery to 100% at once and use your device till 15% or less than 15% and then again charge it full and so on...
This will make your battery backup good as well for battery life

If you are on a custom ROM, try wiping cache and dalvik and battery stats...could help.

According to the Battery Doctor app, you shouldn't leave your phone on charge for more than 9-10 hours(MAX), otherwise it WILL harm your battery.
You should try hibernating some of those apps with Greenify.

Use better battery stat (check play store) or similar app to track draining application.
In this way you can find a culprit

Yes, over charge can reduce battery life.
Accu battery is showing battery capacity only 3600 mah instead of 4000 anyone faced this or my battery is dying

Here is the screenshot
This can have multiple reasons, for accubattery to show a reasonable number you should at least use it for a week.
The supercharging messes up the mAh count... if you only supercharge 20%-50% all the time accubattery will show like 4500mAh.
So just keep using it for a while and see what happens. If you phone is one of the first that were shipped it is already 10 months old. if you use the phone a lot and always drain the battery and charge it to 100% always then the battery will wear out much faster. also heat can wear the battery out over time if you game a lot or live in a hot country then it can affect your battery life span too

Thnx for the clues, now is uodated to 4040 mah, is not accurate as the name of the app, lol my mate 10 pro is 5 months old and is about 6h30 screen on time and performs well my question is it is better to charge when it is on 30 % or wait till he turns off or to make short charging when it is on 50 or 60 per cent. Which method will keep the battery life

first of all: if you are happy with the battery, then dont focus so much on the numbers of an app. If it is enough juice for your days then everything is fine.
Accubattery explains it pretty well with the Charge cycle wear (or whatever it is called).
Generally speaking draining you battery to 0% or chargin it to 100% both means stress for your battery, it is bad.
So try to never drain it to 0% and never charge it to 100%. Accubattery has a scale fot this they call it "battery wear" and chargin from 0% to 100% causes "1.0 cycles" which is maximum stress for your battery and very bad.
If you want to have "0.0 cycles" you should best keep your phone between 45% and 55% all the time. Of course that is impossible but if you have the chance just focus on never letting it drain to 0% and never letting it charge to 100% (the last 10% take too ****ing long anyway, also do not charge over night. 100% for the battery is like a small car with 20 people inside... when the charger keeps the phone at 100% for 5h or so it means high stress over a long period of time).
My last charge charge was from 11% to 85% the wear is only "0.3 cycles", so its only 30% stress compared to charging to 100%. Lucky enough for us the battery of the mate 10 /pro is so big, we can afford only charging to 90-95% and still have enough battery for a whole day.
You shouldn't check it from. This tab anyways
Go to health there you will see the true current capacity of ur battery
