its not posible to calibrate a xperia s(L) battery , it auto calibrates, if you use battery calibaration apps, it just deletes a important file, (which may have ruined your battery)
i suggest keep letting your battery go to 0% then charing to 100% , the battery will calbrate its self

Its hard to know what can be the problem.you should try uninstalling greenify and observe the change.I observed without greenify phone usage is more but with greenify standby is more(thats what I need)

I'm having the same issue, but my phone is a Xperia V.
I have never calibrated the battery.

It might not be an issue; when you turned off your screen, battery was being eaten away and when the screen is turned on it shows the change at that time. Similar stuff happens to the clock.
If you have messed with any system files I suggest you perform a factory reset.

[Q] horrible battery life since KitKat update Sprint g2.

Any other g2 users having major battery issues? Sprint g2, some apps and bloatware frozen/removed. Rooted as well. Battery dropped 38 percent in 4 hours with little to no use. Location services are off. Shows that android operating system using around 40 percent. Any idea of what is causing this? So far, not loving the update and the issues its having.

Absolutely not... Quite the opposite. I'm on a custom ROM but I used ZV7 ZV8 & ZVA before with no issues. That's one great thing about the G2 is the Snap Dragon processors are great on the battery, a charge lasts a long time and the battery never gets hot even with constant tethering and heavy usage. You should try the Snap Dragon battery guru app in the play store at: play.google.com/store/apps/details?id=com.xiam.snapdragon.app which is great for saving juice. Or takes a couple days to get full effect cause it learns your patterns and stops apps from refreshing during times when you don't use them, cuts of WiFi and or data during times when you aren't using it. Also I'd check your battery usage stats and see what processes are draining it the most. Is most likely an app or 2 draining a lot of your battery, so the battery guru will stop that from happening during times that you don't use those apps.

Its very common after a firmware update for a battery to go outta whack. It may be that you need to recalibrate it. After any firmware update its adviseable to so a factory reset at 100% battery level. Then use your phone normally till the battery dies and phone shuts down. Plug in the phone and let it charge to 100% while off. Turn it on, and use it till the batt dies again. Repeat charging to 100% with phone off.
That may solve your issue. Fully cycle the battery 2x.

Thank you @bigpoppa and @sudosurootdev I will try both suggestions. I've got snapdragon app downloaded now. Haven't did a full cycle charge on it yet though. Normally had great battery life, even on aosp roms. Could be that I am just impatient too though haha.

Battery life is greatly affected by weak signals. It drives up the power to get you signal
Sent from my LG-LS980 using xda app-developers app

My signal has actually been a great deal weaker since the update. I live in an.area where there is only 3g/1x data. Used to get around 1.8 mbps download...now only getting around 600kbps. Pretty much just sucks.

I'm having the same issue. It's wakelock WifiOffDelayIfNotUsed. I've tried everything I can think of, but it's completely keeping my phone from deep sleep.

I did one full cycle charge. Took it off the charger at around 10am yesterday. Almost 21 hours later, sitting at 35%. Doing a little better than before. Bluetooth keeps showing on my list of wake locks but it's disabled.

I got the ZVC OTA, then I flashed the zvc .tot after accidently deleting supporting services for voice mail (Skyfire Observer and Sprint Extension provider) after flashing Im at 7hrs 30mins Screen Time surfing web with 15% battery left on first day, before that I got little over 6hrs with 0% battery and all the same apps. Do a factory reset after OTA that might help or flash the ZVC.tot for a complete fresh install like I did.
Just an FYI Swype connect is a known battery killer for some its mentioned on their forums and it sometimes runs even when all connect features are blocked.
Another thing block location services when not needed it will save a nice amount of battery life.

I think its a problem with 4.4.2, google is fixing that in 4.4.3. Also make sure Sprint Connections Optimizer is really off.

The only issue I've seen is Bluetooth showing up under battery stats as being used at around 50-55% yesterday with a runtime of over a day. I'm thinking its just a reporting bug since I haven't used Bluetooth at all and I don't see a noticeable drop in battery but if it is using it I'd definitely like to curb it.
anyone with a similar issue or possible idea on fixing it? Running stock zvc unrooted

That's weird, never had that happen to me. Did you Factory reset after OTA? Sometimes that helps.

I get 7.5 hrs and 15% battery left at 50% Brightness, location and autosync drain battery a lot as I mentioned before. Also use task manager to autoblock Sprint apps and uncheck Sprint Connections Optimizer it eats battery, Lastly Swype connect runs even when online features are disabled and eats battery, there are many complaints about that on Swype forum as well.
Im mostly on WiFI and have full signal due to Airave (no LTE) so I guess that helps too. All those things add up, I'm sure you can achieve that screen time as well.

By factory reset, do you guys mean in settings? I need to reset, but I don't have a computer at the moment so I can't reflash tot.

Urgent! Battery problem of phone problem?

Ok so when my note 2 is 100% it drains quite fast till 20%. Im on phantom v12 rom. Then when at 20%, my sim card signal goes off and after few seconds it shut down.. and i have to charge to get it booted
This happen in stock kitkat rom too. Please tell me why.

This is weird, I suggest you to install 'advance battery calibration' from playstore. 1st full charge the battery then open battery calibration app and follow the steps. After that, use the device at least 2 full cycle. If problem remains, come back here and report. Best of luck.

Try another battery . Most probably your battery is dead .

You and your phone. Battery life after LP update.

So has anyone noticed a severe drop in battery life since the LP update? My phone has dropped 6% using only XDA, on WiFi, and on 18% brightness. I can't go half a day before the bat is at 50%.
Sent from my LG-D851 using XDA Free mobile app

Mine is slightly better
Mine is actually a bit better once I re-flashed stock and upgraded to lollipop, I had some stability issues when I flashed lollipop via twp. the tot restore method helped me.
I'm getting 4 1/2 hours + SOT and It's lasting me a whole day, on auto brightness.

My battery has been a bit better when the screen is not in use(i.e. sitting in pocket idle or streaming music), but it seems worse then before when the screen is on.

Ya I'm not sure what's going on, but I find I am having to charge it more often during the day than I did before.

I've read about the heat issue but I haven't had it, BUT I did have to do a reset because my phone wouldn't after I first installed lollipop so that might be why I haven't had that issue.

Mines not that great either. I have greenify but not the xposed aspect, I have battery guru, I even installed a script which I normally don't do. All of this has helped minorly. Nothing like it was for me though. I factory reset when I flashed. Waiting to see if reports from official Ota has any differences.

Mine got bad first. Then I did a full factory reset and now its pretty good. Had 0% down after 12 hours at night. Normal workday usage went down from ~40% to ~25%. So instead of charging every other day I need to charge every 3 days.

I have thought about doing a factory reset to see if it helps. I know there was a cm app to backup your phone but idk if you need root. I have chosen to not root my phone, and wonder if you guys know of a good app to help backup my phone before doing so. Thanks.
I am looking into helium, has anyone had any experience good, or bad with this app?

Helium works well with early kitkat builds. the cloud backup option blows though. not too sure about using it on lollipop but being that it didn't work to well with late kitkat builds i doubt it'll be any better with lollipop.
also my battery life has gotten plenty better after updating and starting completely from scratch.
currently i'm sitting at 35% with 14hr and 17 min run time, auto brightness, wifi turned on and jumping back and fourth between lte because my router is going dead...

Do a clean flash or check what apps are consuming the battery. I use Accubattery to monitor the battery. Gsam is also good.
