Arc S, draining battery - Xperia Arc Q&A, Help & Troubleshooting

When i bought the phone, the battery was draining really fast but i thought it was normal as the phone is new. After some weeks it got better, the phone could hold 3 days sometimes but since this week the battery is draining fast again, i only installed some games but already deleted them thinking that they could be the problem but they do not seem to.
Yesterday at night, the battery was 22% and i put it charging, as it reached 100% i took it off and went to sleep. Today when I woke up, it was only 80%.

Battery bug with 2.3.6 update?

I installed the 2.3.6 update using Kies. I have fewer apps installed now than before the update and the are no apps installed now that weren't before.
I checked my battery life under about phone and found that in 8 hours and 7 minutes of up time, my phone has been awake for 7 hours and 59 minutes of it.
I'm not sure what's causing it, but I've started deleting apps one by one to see if I can find it.

I have the same problem and my battery life sucks pretty bad.
Sent from my SGH-T989
Battery life got shtyier and so did internet speeds. New update sucks
Mine isn't doing that. I'm getting days on a charge. Leaving wifi on does drop this to one day only.
My battery life seems to be better than before. Sorry guys.

[Q] Phone seems to be heating even on idle

Hey guys there seems to be some sort of a problem with my phone now.
It has never happened before.
I realised that my phone was pretty hot last night, even on idle! It's as if it's running a Tegra game or something. And the battery goes down at a rate of about 50% in 3 hours.
I checked the task manager and couldn't find anything that is fishy.
What else can I do?
Thanks in advance

As you can see, my phone is in deep sleep mode the whole night.[Well the both of us need some rest, right?]
Now, in Battery, my phone's screen is indeed off, but it says that my phone is awake all the time!
And finally, the weirdest thing happened. Before I slept, my phone's battery was at 24%. After I woke up, it was at 31%![As you can see in CPU Spy Plus, Juice Lost is -7%]
SO, any ideas?

Ah. This is not surprising. I assume when you just unplug your phone from the charger awhile before you left your phone and went to bed. Logically Lithium battery is recharged but those charges require some time to "kick-in" Your phone itself is using a setting that requires minimal idle battery consumption. So when the charges starts to "kick-in" but you disconnected from the charger this happens.
Happened to me a lot. Don't worry. Issue

Strange battery reading (Jumps from 5% to 49% on reseating battery)

Power is draining so fast on my Note II recently. I usually use it for like 5 hours and I have to swap the battery.
Today, the battery is draining as usual. After 7 hours use, it was down to 5%.
I did a proper shutdown and removed the battery. I found that I forgot to bring my spare battery so I just reseat the battery and plug in the cable to charge. When the phone starts up, I amazing thing happened. The phone is showing a battery level of 49%?! Huh...?
I don't understand what's going on. Could it be the problem on the phone or the battery or the OS? I've heard that the battery stats in OS is no longer used for the recent mobile phones because the battery nowadays are "intelligent" and stores their own data. I wonder how can I reset the stat for the battery.
Then I do a restart, this time the battery level jumps to 61%. Wow...

After using Navigation GPS for 20min, 10min calling and some 20min surfing and 10min chatting
6 hours of screen ontime for 1 day, or two days with 4 hours screen. Same as marshmallow, great battery life for a phone and standard for this device.
Hey, how you get 4.2%/h? My phone (A5 2017) discharges about 10%/h while surfing web, fb, messenger, snapchat... almost on all apps
