New battery does not hold charge

New battery was drained and fully charged while the phone was off.
Now it drains to 15% after less then 12 hours of average use.
When charger is unplugged the battery imm goes down to 97%
what is the best way to improve the battery performance ?

Don't use it as much
Everything has a work in time, your phone needs to forget about old battery and dance with a new partner. Give it a chance...
Oh and search is a good thing. This phone isn't cutting edge anymore.

12-13 hours battery is good.

Did you get this battery from china?
It probably has like 800mah.

Is there any battery today that does not originate in China ?
It is marked "SAMSUNG G7 1500mah".
I already tried to calibrate the battery about a week ago using a market application that claims to perform a reset of the battery stats.
after the reset I drained the battery for 3 days and recharged while the phone was off every night (during those 3 days).
then for the first few days the battery actually held up nicely reaching 50-60% after 12 hours.
after a week or so it started to drain more rapidly reaching 15-20% in the evening.
It also fails to hold 100% when the charger is unplugged, going straight to 97%.
should I try another battery or is there a another way to calibrate the battery ?

What does your 'Battery Use' say is using most of your battery?

Its still quite possibly a fake samsung battery. Did it come from a reputable seller at least? If yes return it.
Heres an example of battery life with a genuine samsung 1500mah battery

Hey BenKranged
What APP did you use for that screen capture? I know this has nothing to do with this post but looking for one on the market and there are so many to choose from.

I've had good luck with the ShootMe app. (Sorry, I'm not BenKranged, but I thought I'd throw that out there.)

Is there a way to identify a genuine non-fake G7 battery ?

That's how mine looks. My battery does seem to drain fast when I am actually using it. But, also when I'm not using it, it seems to keep at a steady battery level for a while. I guess it's a trade off. I also use Juice Defender which definitely helps.

I probably used juice defender for about 4 months. Then I tried running without it and found I got equal or better battery life.

[Q] feel like returning after battery life ?

Anyone felt like returning this phones after a week cause of battery life?
Im not cause its not that bad and maybe a custom ROM may be able to work on that just looking for other people's experience and what they think thanks!

It's useable with a few temp.. tweaks .
The bottom line is this all occurs with lollipop in general S5 was great on kitkat ...until 5.0
It's not the phone it's features and O.S
People are disabling Volte and WiFi calling it helps a lot
I wouldn't return it over battery life yet the camera is way to good
Give it time We get roms soon and mods it's I take back everything +I said
Samsung needs to take back every s6 and Rethink there whole O.S
For a 750$ flag ship release its so buggy it's hopeless .
Camera is only worthwhile feature

Do one factory reset and set up phone again and disable VOLTE FOR NOW under Phone /More .
Cycle the battery meaning charge filly and let it fully drain as far as you can before recharging again .Another words don't fully charge it when it hits 40%
This is true the battery's learn a drain span
I'f you recharge anything above 10% it isn't gonna learn it's max capacity Takes like a week.
The main fix is Volte disable and WiFi calling

i turned off volte i dont really see the need for it i mean its a phone call why do you need such high speeds lol my phone is at 2 percent waiting for it to die lol thanks

If it wasn't for the rapid quick charge I probably would have
returned it but the fact that I can top off in a half an hour it's really not a problem getting through the day.

I think it has something to do that the phone is not going to deep sleep, i rooted mine and flashed a custom kernel, now it does deep sleep and battery is ok now

While battery life isn't as good as some phones I've used recently I still got 5hrs SOT yesterday. Not bad at all.

That is pretty good for this phone ....
Has anyone tried going into Developer Options }Limit Back
Ground Processes to 4 ?
I wonder if this barely slows the Phone for most things but might give an additional ( wild guess 10% to 25%) Battery Life.
I don't have one but if this works....be easier for me to decide.
I may put this idea in a separate Thread.

Yea I can't complain about battery life. The screen is so ridiculous I end up using the phone for no reason, so my usage at least for now since it's new, isn't my normal usage.

Should I get one?

Hello dear XDA friends, Although I don't post a lot I still love you all .
Anyway, I am really tempted to get a Mate S ($/€319) after my LG G3's screen basically broke in half, the battery exploded and the touchscreen only working 10%, it's basically useless right now and I need a phone to replace it for a while until I decide what's going to be my ''real'' phone (I hate Apple but the 7+ Camera is amazing but then again maybe note 7 refurbs will be cheap.) So yeah I need to bridge the gap and I want to gift it to a relative when I'm done with it.
So is it worth it for 300 bucks?

Hi,
I have the phone since 3 months now (rooted and latest rom version) and it is in overall very good but the battery. Screen is very great but although there are a good device manager, it doesn't stand a full day without reloading.
Also you can see from the different posts that this phone is not very popular among Android's cooks. So not a lot of answers and not a lot of tricks and tweaks. I regret the time I had a Nexus 4 where community was very active. Anyway, as I am really focused on battery life, this is the real flaw of this phone for me. But I guess there are not many phones that could do better.

What's the longest screen on time you got?

It actually depends what you gonna do with this phone.
I own it for last 8 months never really felt need for better battery during normal usage.
My typical usage with all the time brightness at auto and slider at max ( which on huawei even when inside usually means 80-90% brightness ) and outside always even when is dim day is 100% or boosted screen mode ends up with average 4:30-5h SOT with around 18-20hrs on battery. This is with about 60% wifi 40% 3g.
This includes bunch of social apps, youtube , music, calls, sms, light gaming of around 1hr per day.
The great thing about this phone is its soc and screen, the to S-amoled it never gets hot thus for it doesn't drain battery life fast like snapdragon devices.
Biggest fall of this soc is its GPU it isn't as good for heavy games like s810 devices for example.
If you're not a gamer I highly suggest this phone. If you have more money I suggest p9+, its a beast in all regards.
Here my current battery life stats

As you can see, I charged my phone and unplugged at 00.14. Wi-Fi off and no mobile data, no screen on. No apps running apart from home launcher and myProfile. All others are greenified. So in around 8h sleep it decreased by 20%.
I tried many tricks and I consider myself skilful for this (my LG G2 could last 3 days) but cannot do better with this one. The ROM is not good enough yet and update frequency is not good.

Got the LG G4 so this one can be closed

Help on battery drain.

Can someone help me, Im having a battery drain on my lenovo a7000-a,
I already bought 2 Batteries and change roms, but still my battery keep draining and Ive already tried all those calibrate methods around the internet.
From 100% down to around 80-60% is fine, but when it reaches around 60% below, my battery starts draining for like -1% every 30 secs.
Tried different roms and a few apps running.

Lol welcome to the club.
The battery drain is a classic feature of MTK chipsets and that's a reason why people don't prefer MTK here at xda.
The drain can't be fixed. The kernel sources seem messed up by mtk and unfortunately even though I'm the only one who reached to extreme depths in mtk source in this forum, I couldn't find a solution. Maybe it's just a hardware level issue. Maybe it's an issue with the chip's design itself. One thing I found out was that though we can't fix the drain, we can move it to different parts of battery %. Like you can drop the 20% right at max 100% but keep the rest 80% fine. Or, as by default, you get a drop from around 30-35 upto 15-10%.
I hope I made it clear enough

Am I the only one who thinks that this is a way to make the battery capacity seem bigger/phone lasting longer? That its not a bug but rather a "feature" for manufacturer to make buyers think that phone has better battery than it actually has ?

Nope, I don't think so. During the last few battery % it lasts suspiciously too long, and after the phone dies, you can reboot it and still find 12% battery suddenly come up.
So I think it is actually a bug and a serious one

Question Accubattery showing Battery health at 47% for a new phone (1 month old)

I purchased this about a month ago. I have been reading a lot of posts out here about people having fairly low battery life. So I had installed Accubattery to see if the discharge is abnormal. I checked today and it seems like Accubattery is claiming that my battery is only at 50~% health. Now I am unsure that if this is because it is a genuine fault or because this phone is supposed to have 2 2500mAh batteries and Accubattery is detecting only one of them. Any idea about this?

I've had my 11T Pro for roughly two weeks and I have the same issue.
It doesn't read charging speed correctly which confuses it's health calculations.
I'm sure your phone is fine.

Those SOT numbers seem erratic. Some reasonable, others look impossible.
When you're using the browser not watching vids the usage should low.
As the previous poster mentioned it may just not have good sensing for battery usage.
Accubattery is only as good as the data it's getting. Even then it can screw up. I don't understand what's going on there.
Rather strange. I don't have that phone so I don't know what it's nominal run time should be. If it's running cool and you can get 8-10 hours SOT you're probably in the ball park.

Hmmm, okay. I'll continue observing my phone's behaviour then. I do get over 8-10 hours SOT on medium usage. Additionally, I read from other threads that the 120W charger isn't charging the phone fully and it makes sense to charge with a lower power charger. So I will try that as well. Will keep this thread updated if I see any improvements.

Accubattery doesn't work well with dual battery setup, that's why it's showing Battery health at 47%.
Set design capacity to 2500.

11T PRO has 2x 2500mah battery for ultra fast charging. Set the design capacity to 2500 and you will be fine.

This presents a potential problem in the future as one battery can degrade and fail independently of the other. You really need to be able to monitoring both.
If the manufacturer designed it properly each battery should have its own power controller in a perfect world. Not sure if this is so on any of the dual battery phones...
