Ok so after a hard reset and at 100% charge my HTC Radar says 1 day and 15 hours remaining. It has been like that for a few days. After about a week, 100% charge results in 20 hours remaining life. Eventually after a few more charges it averages at 15-17 hours remaining battery life. That is a big worrying decrease. These figures are always noted after a 100% charge and leaving it to settle for a bit.
So I started thinking what could be causing this decreasing stand by time?
Two theories:
1. It must be an app as I got excellent stand by time from a hard reset and with no additional apps so maybe a particular app is playing with the battery meter?
2. Could it be leaving the phone over night plugged in is doing something to the battery? Maybe I should unplug it as soon as it gets to 100%?
The strange thing is it can't be the actually battery degrading over time as the phone is new. Also, I have recently flashed a custom ROM to my Radar at a point when stand by time was at 15 hours at 100% and after the flashed ROM the standby time went back up to 1 day and 15 hours. Something is not right. It must be an app.
Any other thoughts/theories or anyone else in a similar situation?
Discuss please so we can all learn something to hopefully solve this problem for other handsets too!
My guess: calibration. The system estimates your runtime based on previous runtimes, that's why it's getting lower. Did your phone actually ever run that long, btw?
yes it did. very very close. i was amazed.
and does it now actually run out faster? I have noticed this on my ipod. It used to tell me 1h battery remaining and it would run for another 3h until i got home and another 2h the next day (when I noticed I forgot to charge). Also, are you using your phone more now? The biggest battery drain is the display.
Remaining battery life is estimated as follows:
Immediately after being removed from the charger is based on previous usage charging.
After this time estimate is based on current consumption.
In the first week after hard reset or install ROM the period are recorded in the system.
After a year of use of personal phone (HD7) and trying different rom and different settings for gps, 3g, edge, and light i found that the consumer eating large battery . After a more detailed study will say that is the main consumer.
Thanks for your comment Ovi but this is not about how the consumer is wasting the battery by usage. The question I raised was about how the standby time varied at 100% after a hard reset and after weeks of usage at 100%. The stand by time decreased without using the phone after a full charge. That is what is puzzling me. In theory it should be the same stand by time no matter how long the phone has been owned and the rate of discharge is due to usage - agreed.

I've had the phone since Sept 6th and this is 4th day I have my phone.
My battery life has been draining like crazy. I don't have a data plan, but I do go on wifi sometimes (not very often, and I don't keep it on for long). Maybe in total an hour to two a day.
I wouldn't say I am a heavy user, I don't play any games or watch any videos nor listen to music at all. I only sms and download apps.
It's been 5h 42m 35s since unplugged and my battery life is down to 57. I hardly use it, my settings are pretty much the lowest.
It says
Android System 40%
Cell standby 21%
Phone idle 13%
Display 12% (weird, since I have animations are turned off and I used lowest brightness)
Camera 6% (I took 3 photos)
Wifi 4%
Maps 2%
Dialer 2%
about 2 hours ago, I rooted my desire since I've read reviews that it makes it faster, prolongs battery life and what not. (plus I could do so much more with it later on). But my battery was still draining at like 1% every minute and half that I touch it. (I also have task killer, but I don't kill task very often)
Then my friend suggested I get SetCPU (which I did) around 2 hours ago after I rooted my phone. Then I went out and hardly touched the phone unless I received sms, or to check the time. And it went from like 69 to 56 (within that 2 hours of doing nothing)
I've searched the forum for extending battery life (and googled as well) and read other users who have the same problem, and I pretty much did what was recommended but it's still draining.
I can hardly make it through the day!!
Is there any other way that I can charge it (when to charge it) or.. do you think it might be my battery's problem? Should I buy a new one?
Thanks for all the help again (I know this kind of thread has already been done, but that was in like April)
Your battery takes time to settle if it's a brand new device. It takes a few charge/discharge cycles for that.
If after say 14 days you are still getting poor life I'd try calibrating it. Instructions are HERE.
thanks! i will try that if my battery life still drains this crazily in a week.
I am getting the phone for christmas and was just wondering if I have my parents charge it the night before, will it last me all day? What is battery life like on the first charge?
You'll likely burn through it pretty fast on a first charge. Best I know, it's not optimal until about 3-4 cycles.
Mine was pretty horrendous at first and then again for the following couple of cycles after that. Now on 4.0.2 and a number of cycles in and I think the battery life is stellar when you consider the screen size. Pretty similar to my GSII so cannot complain.
My advice. .. take the charger.
Regards.
I got about an hour of continuous tinkering after a 10 minute charge. Had to plug it in after that.
The first charge will be the longest lasting charge you will ever have on this battery - depending on your usage.
LiIons degrade a wee tiny little bit with every subsequent charge.
Thanks, I can't wait to get it.

While this is true, I dont think its calibrated the first time.
I got my nexus yesterday and charged it up from 50 to full and it was literally at 0% 10 hours later, today is a different story, I've been able to get about 12 hours of use out of it and have about 35% battery left

Calibration only affects the battery icon, if they use poor logic to calculate the charge. The system can read battery voltage precise to 0.001 volts and it's actually quite easy to gauge a LiIon cell: 4.200 V = full, 3.600 V = empty (without load on the battery)
My first charge only lasted about 5 hours, and that was because I was playing with the thing the whole damn time. ;-)
My first charge
This is what I got on my first full charge. Was on Wifi for most of the time. Bluetooth was on often in the beginning to transfer files.
Used GPS for like. Facebook sync was off. Gmail, Google+ on. No Reader, Google Photos, Docs sync.
I bought the extended battery and it both were about 40% charged. You'll want to burn it down completely till it powers off, then give it a full cycle.
You'll kill it just by setting it up, playing some games, playing with the OS, reading XDA Rooting guides, taking pictures etc.
Just kill it, then put it on the charger while you get a shower and dressed.
...then you'll probably kill it again by the end of the day cause you can't stop plating with it.

Ive read that the way weve always used with the wiping of battery stats actually doesnt do anything.
I got a GTmax 3500 mah battery but the phone turns off at 0, even though it has power, its sitting at the recovery screen and is just fine. I was wondering, do i just leave it here to drain it, or do I have some other method of calibration. Im pretty sure its going by its old stats because it drained in 12 hours and turned off. I SHOULD get ~23-24 hours on the new battery.
Yes, it has been determined that the battery stats file we used to wipe does absolutely nothing to prolong the battery's charge on any Android phone. The only thing it does is wipe out the statistics that we see for what is using the battery. Personally, I've never noticed any difference in battery longevity when wiping the stats file, so I stopped wiping it long before this information came to light.
As for your issue, the phone turning off at 0% seems pretty normal to me. I'm not really sure what your concern is. Just because you can access the recovery screen doesn't mean there is enough power to let the phone run normally. I would let it charge for several hours before using it again or at least leave it on the AC charger while you use it. It is also not a good idea to let the phone discharge down to 0%, as this can shorten the lifespan of the battery. Typically, the battery power meter is pretty accurate. Plus the battery should be fully charged before use. It is speculated that if you condition the battery itself (fully charge, then fully discharge (the one and only time this should be done), and fully recharge it again), you may see better life. Considering that on a typical day, I get about 5 hours of heavy use before I have to plug it in, I would welcome 12 hours without having to charge.

Thats strange. I got some friends with iPhone 4S and they get over a full day with some moderate use. I get 12-16 hours tops. I can easily drain it in 8 hours. Doesnt seem like it should require mid day charging.

It is very difficult at best to compare iDevices and Android devices. The hardware and software are completely different. Regardless, I also know folks with the iPhone 4s. About half of them drain their device within 5 hours. Constantly doing stuff... The batteries on most smartphones are just not up to standards with today's hardware. At any rate, the rest of the folks I know with the iPhone 4s are more moderate users. They get about 7-8 hours. One person claims she gets 9. It depends on usage. Plus, as avarize stated, underclock, a decent kernel, screen brightness, etc... And SetCPU is a great app (even for non-rooted devices). Also, constant text messages tend to drain devices. It just depends on how you use it.
Hello all,
I bought a new Z play to replace my ageing phone, and I have mixed feelings about the battery life. The phone has received universal praise for its battery life, and while some of it is true in my case, I can't seem to get those high SoT numbers that everyone brags about.
It's very difficult for me to break the 6h SoT barrier, and I consider myself a light user: whatsapp, browsing, some reddit, and the occasional music (through headphones). I don't play any games, or perform heavy tasks. Also the phone is connected to WiFi 85% of the time, get decent signal, and the screen is set on auto-brightness.
Running latest version of the stock rom, and I performed factory reset + wiped cache + reset network settings countless times as per suggestions.
Attached some stats for 50% that I just took.
Is there something I'm missing?
Take it with a grain of salt, just because people brag about numbers does not mean they are real or obtainable by everyone. Battery life will vary for every user and phone. The time you have is in the acceptable range and I would not worry.
Yes, even I have never achieved the 8-9+ hrs of SOT that's I've seen in some threads. Based on my usage I get a minimum of 6.5hr SOT with the phone lasting a good 25-27 hours before I have to plug it back in.
Since the phone is new it might take a few cycles for the battery to truly show its stamina.
Those answer are definitely right. It all varies on the users. . Also please makes sure you have bluetooth and wifi scanning off. (Location> Scanning > Bluetooth & Wifi Scanning) Another factor is apps. Get rid of facebook and facebook messenger. Apps that use GCM eat battery like a range rover eats gas. I've hit 8--10 hr of SOT before. Let your phone get use to your daily activities. I believe it'll optimize itself over time.
It's normal.
I was also getting earlier 5-6 hrs SOT(When the device was new) but not I'm getting 8-9 hrs SOT.
So as your phone is new it might take few cycles for the battery to show its full stamina!
Cheers!!
Thanks for the replies and for putting my mind at ease.
Bluetooth and wifi scanning are off (forgot to mention that).
Anyway, I understand. Those insane SoT of 10+ are best case scenarios with careful use of the device. Still happy with my current capacity (anything which lasts until the next morning is great).
And yep, the phone manual (who reads those anymore), did mention the battery taking a few cycles before reaching its capacity.
Now, for a different issue. If I'd like to disable turbocharging/quickcharging my phone, would a USB C to A cable coupled with any charger (including the quickcharging ones) do the trick? Based on my understanding, the cable limits the chargining power, so any regular (quality) C to A cable should restore normal charging speeds even when using a fast charging charger. In case you're wondering why I'd like to do that, it's because the phone gets way too hot for my liking when using the Moto turbocharger and I'd like to reserve that for when necessary.
Well, guyz do have a point.
The screenshots are showing you have almost 3hrs SoT after day and a half. This is normal.
Those >10 hrs of SoT aren't achieved with careful usage. Coming from my experience, I got 10.5 hrs SoT with 10% battery left, BUT, in one day. My Moto can last up to 3 day with one charge, but in those 3 days I'll have maybe 4hrs SoT. So, in average, my Moto lasts up to 2 days with 6/7hrs SoT (I mostly use FB, Messenger, WhatsApp, Viber, YT, Instagram, stock 6.0.1). It simply depends how you use it. That big, almost 11hrs SoT, I could only achieve on weekends, coz otherwise I don't have the time to stare in my phone so much.
On that other thing, Moto does get pretty hot while charging. And you're right, the cable does limit the charging power so it will probably work.
I was one of those users getting 10h SoT early on. But I was doing that inside a 24h usage window. Your 50% stats have you stretched out to like almost 3 days off charger. Idle time vs. screen on time is ALWAYS a trade-off.
I look at battery drain in terms of drain rate at idle, and drain rate with screen on. Early on I was seeing 6% drain per hour of screen on, and 1-1.5% per hour screen off. So basically 5 hours of idle time costs you 1 hour screen on. Those were my numbers on the original MM build. My battery life has gotten worse with every software update. I have NOT done a factory reset, mostly because I don't want the hassle and I still get a day off normal use with plenty of battery to spare. But I usually see 18h off charger and 3-4h SoT in a normal day, and that leaves me at 40-50% when I plug in.
Looking at your stats, if screen on costs you 6% per hour, you have 17% worth of screen on drain. That leaves 33% idle drain over 38 hours, or sightly less than 1% per hour idle. Seems pretty darn good to me.
Your cell signal is definitely not helping your battery life. Switch to 2g when on wifi, your signal bar should be full and it'll probably help your battery life.
Enjoy the fact that this phone lets you keep BT/WiFi scanning/Facebook/etc. on without having to worry whether or not you're going to make it a full day. I use all that stuff, have multiple live widgets updating, brightness at least half way, T-Mobile Digits running, and still make it a full day. Additionally, it's great to know that if you do have to make it 2-3 days with minimal usage because you don't have a charger handy, you can. However, I'm willing to bet that 99% of users are able to charge their phone daily. To those users, I say enjoy all the features and don't worry about it.
Really depends on the screen brightness...I can hit those number with my screen brightness turned down a good bit...probably around 30 percent and auto sync off...if i have brightness anywhere above 60 percent then battery life drops a good amount...still well enough to get me through a 12 hour work day but there is a difference

So I've noticed some weird battery behavior on my Pixel 2 XL and was wondering if anyone else has noticed this.
I normally like to ;et the battery drain down into 5% or so before plugging it in and letting it charge through to 100%. I started noticing that a full charge would take me nearly 2 hours fully charge. A couple of times last week, I had to step out and the phone was charged approximately 95%. I unplugged the charger and walked to my car (about 5-6 minutes to get to the car) and when I looked at my phone, charge had dropped to 88%. Over the next few days I noticed this kind of excessive drain immediately after unplugging the charger. Aside from this, I still achieve 24+ hrs of battery life on a single charge so I am not sure that it is a HUGE issue, but one I felt shouldn't be happening nonetheless. Last night the same happened - unplugged around 95% and i literally saw the battery indicator go to 93%, 91%, 88% and then stop at 87% in about a minute. I immediately called Google support, shared my screen, and after speaking with the person on the phone - i was told I should definitely RMA, which i did..so I have a replacement coming.
I don't use always on display or always listening and I am extremely good at clearing open apps before I put the screen to sleep. I have noticed this at home, on my wifi as i always need a charge later in the day when I'm home from work. Also, I use the OEM charging wire and brick.
Anyone else notice this ?
I have not noticed battery drain fast after unplugging at full charge level. I would say you probably should RMA the device. Also it is not good to let lithium-ion batteries go down to low levels a lot like that, it will degrade the battery faster. The less you let the battery go down to low levels, the more charge cycles you will have, which means long battery life over time.

I definitely did RMA, it was a painless process.
And I always thought that maximizing the charge of the phone (letting it get low, then charging up) would actually keep the battery healthier as it would reduce the # of times I charged it. Am i way off base with my logic for that?!
Going into my third week with my 2 XL and I haven't seen anything abnormal regarding battery drain.
I do practice the method of unplugging at 85% and plugging back in around 15% (per Accubattery's reco, and other reading done online)....
There's no proof that it helps as suggested, and while I realize that only allows me access to 70% of the battery's charge potential, I'm rarely, if ever, away from a plug for more than half a day.
This theory worked well in my 6P until it got the intermittent BLOD... My battery health was around 84% (via Accubattery) after 17 months of pretty heavy use.
Again, not sure it is solid fact or not, but you could always try it for a month and see if there is any noticeable difference in battery drain.
Thank you for that insight! I will absolutely do some research. You're battery health after 17 months is really impressive. I just switched from a Nexus 6p that was definitely showing signs of wear after 2 years of fairly standard use. I hadn't used accubattery, but I will download it on my new replacement and monitor results.
I will say though, that aside from that slight blip i noticed - the battery (andOS optimization i'm assuming) is amazing. I get through a day plus easily. So, anything I can do to keep that consistent or squeeze more time out of it is a no brainer.

Lithium-ion batteries work on charge cycles and are happier between 50-85% charge levels. You cannot really "overcharge" the battery because the phone will stop charging at 100% and just trickle charge to keep the battery at this level. But unplugging it after full charge defiantly wont hurt. If you keep the battery at higher levels I would't be surprised that you would get 1500+ charge cycl.es out of the phone before any real degradation which should easily get you years of good battery life. I find the battery life on the XL to be awesome and it lasts me throughout the day with still 40% battery life left and that is with pretty heavy usage.
