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.)

Thanks I will give it a try

Shootme is what I used.

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] Why does android's standby time suck?

I've used around 5 Android phones (starting from 2.1 now up to 4.3) and for some reason, they all have a pathetic standby time. When I say standby, I mean when you press the power button and it turns the screen off and you don't touch it. Why is android the only OS that has this problem? WP, fine. IOS, probably the best one (only good thing about it).
I've tried different kernels, using no apps from the play store at all, turning off Google's location service, using greenify, and a bunch more. My battery still drops to ~70% at 4:00 starting at 100 at 7:00. When I briefly had an iphone and windows phone, I always was amazed at how my battery was around ~90-95% at 4:00. I know most people actually USE their phone during the day, so its probably not as noticeable.
Does anyone know the real reason for this? By real, I mean the deep down reason for this. Is java just a hog?

I think the main reason is the backround apps that are running. I used my old sensation just as a phone and so I deleted all the apps from it (Facebook, Viber etc.) and the phone lasted 5-6 days on standby with a 1 year old batery. Before I removed those apps I couldnt get 2 days on standby. I think backgrounfd apps in Android are allowed more "freedom" so they use up the CPU while on standby. That is my experience and opinion.

Yeah I thought that, but I said I tried it with no apps installed. Same thing.

Weird, I don't experience that kind of massive stand by drain.
If I turn my screen off or let it time out, my phone can sit for a almost a couple of days before it shuts down - sometimes two full days. This was true with my Nexus 4 and Galaxy S3, and now the One.
So I have no clue what you're talking about, generalizing Android like that.

i disagree
My battery drains 1% every six hours

I'm generalizing Android because I was talking about "Stock" android. Not what we do here. I really have to find a fix for this. I dont know what I'm doing wrong here.

Mine also has great standby time...

I am talking about stock Android as well. I have had great battery life with my last three phones.

I've had no such problems with "android" in general. Some roms / apps yes. But after fixing those issues it was pretty much what would have been expected / what reviewers/other people get.
I would recommend getting something like gsam battery monitor and let it run at least a day and then post some screenshots. Maybe we can give some concrete advice then.

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

Normal is relative. Is it a bit on the low side? Most definitely. Normal? Maybe. It really comes down to the apps you have and how you use your phone. I personally get about 5hrs SOT and I'm fine with that. Standby drain is more important to me than SOT. There are battery saving tips and trick you can try to google or youtube.

My phone drains like 3% per hour on IDLE. I don't have AoD nor anything in particular that should be causing this drain. I have no idea why. The battery life seems to be fine for actual usage, but teeeerrible for AOD.

3% per hour no AOD is bad. You have an app causing major drain for sure. You might have to deep dive in your battery stats to find the culprit. Last resort would be safe mode to see if your able to reproduce the issue. You should go to the battery life thread and ask around.

I'm not sure what it could possibly be since my old Note 8 did this too, but it alternated every other cycle or so where it would drain less than 1% or 3%+. I exchanged it for a new one and this issue is happening again except it was completely fine for the first week or two. There was no app that I downloaded between the time that it was fine and not fine.
I guess I'll repost this in the battery thread.

i am not losing battery overnight as much as you guys, my problem now is i can't get 6-7hrs of sot anymore, 4-5 is as much as i get, and it's only 1 month old.

There was a thread about Android OS drain.

I miss my note 4. I use to get around 5-8 sot. With this phone only 3 and half hours. That's with everything turned off too. On my note 4 I had just about everything turned on. Will be waiting for the note 10 to release then I will buy the note 9

Real battery capacity?

Hello everybody! I own a Huawei P9 running Eva-L19 version. And using whatever root app inside my phone, they all shows that my phone has a 2900maH battery. What seems weird is that on every site, GSMArena etc. they all say that Huawei P9 has got a 3000maH battery. Few months ago I've dropped my phone and crack the screen and went into factory, I'm thinking would it be that my battery has been changed...? I don't remember what is the battery capacity showed before it went into factory, thats the problem! It would be kind for anyone to confirm with me what's their battery capacity. Thanksss

Normally wiping battery stats dont do anything in newer devices/android versions(in terms of making battery last longer), but you can try turning off phone, charge it to full and wipe battery stats. Maybe battery was disconnected and phone dont see it properly(but I doubt it... )
As for my phone Its 3000maH on all apps that check it.

Its just a number on some apps. It would be sad if your battery life would be worst than normal. Its imposible to say how long battery will last because everyone use phones differently, they have different apps working in background and features enabled/disabled but no matter of OS version average should be two days before battery on P9 reach 5%
And taht is with LTE turned off(that is one of most power hungry feature in every phone. Tip: just dont use it, HSPA is enough to stream even 1080 videos)
I normally have 40% at the end of the day because I have Gear Fit synced and I use NFC and GPS all the time, but even if phone would have 2900mah battery difference should be not bigger than 5% So dont worry about it that much.
