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...

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%.

Hi guys~ Here wishing everybody Happy Boxing Day
OK, the question is, I don't know my phone is really in deep sleep mode or not.

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

Has anyone experienced a fluctuating battery level? After a full charge, unplugged and sitting. 15 mins after unplug inturned off wifi due to battery being at 98%. 15 mins later its 100% again. Then later its lower, back up, then lower again..

Upgraded android and switched to otterx and still getting fluctuations in battery. I guess no one can seem to comment on it since its been viewed so many times and none of you have anything to say.
Another screenshot of what I'm talking about.

I never check battery percent that close, because it's just an estimate, based on what the device believes is a full charge, current voltage, and current amps.
Could be a faulty battery, could be a bad battery connection, could be a bad charger, but some percentage jumping is normal, how much varies from device and user.
Hey people!
Would like to know what is your battery life is like with Nougat with you A520F.
Post your stats and compare.
i for myself was wondering cause the battery curve in the Battery stats was very steep compared to others i saw.
some useful apps :
AccuBattery
BetterBatteryStats
Battery Charge Limit

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
1- I have a strange battery issues sometimes I get more than 8hrs SOT for about 80% then I get less than 3hrs for the same 8hrs the next charge. (Only browsing and social media apps no games)
2- Also the more strange that the phone is always AWAKE even with location and bluetooth off and I can't identify the reason behind this drain (I lose more than 10% while sleeping)

3- Another strange issue is the battery status gets deleted randomly ex) the phones is active for more than 30 hrs and when I see battery status it gets me the usage for only 15 mins or 1-2 hrs and maybe after some hours I do the same thing but it shows the status for even earlier usage that didn't show for the previous trial
Any help ?
Check your wakelock with app like 3c battery stats.
there must some apps that has high wakelock.
Just like Health apps.
