What kind of battery time are you guys getting on the original battery?
I've had my phone for about 14 days now and im not getting more than 12 hours on a charge.. the first week iv'e been using the phone alot.
I have alot of apps installed and im wondering if that could have a impact on the battery.. i have tryed using a task killer and without..
From the battery usage statistics page the screen is definitely the one that uses the most. Voice calls is number 2.
Will all applications show on the battery statistics page or is this something the applications have to implement?
Sent from my HTC Desire Z using XDA App
My battery has gotten better since I got it. But I have been doing a few things to help my battery - e.g. I completely drain the battery (until the phone doesn't even turn on anymore) and then fully charge it overnight.
Read about task killers and Android here: http://forum.xda-developers.com/showthread.php?t=849974
All apps will show in the battery usage statistics. If the screen has been using the most power, that means exactly that - you've been using the phone a lot and as such the screen has been taking up a lot of power.
I would recommend though to try to completely drain and then overnight charge, and repeat that cycle as often as you can.. I'm no technician, but I do think how you charge the phone matters
i've read about the task killers and have decided to uninstall them compleetly and let android do what it wants.
Regarding the charging, i have ran the battery flat out almost every day..
Im going to try a few different charging methods and see if there is some difference..
however i suspect that if the indicator is saying 100% charge, thats exatcly what it is whatever the charging method. (i hope)
It does get better. When I first got the phone I was getting about 14 hours. Now I'm getting about 30 hours or so.
JuiceDefender and setCPU help preserve battery life, too.
I am lucky to even get 12 hours with minimal use. No calls, just some texting and maybe browsing my bank website. Screen is always the killer for me, even on 20% brightness. If I go lower the screen actually flickers.
I bought the red HTC Chichitech batteries and they didn't help me at all.
Tried overclocking module, didn't change much.
The only app that ever shows any significant battery use (over 5%) is Maps, when I use maps.
i always thought completly draining a Lithium-ion battery is a bad idea?
Yes, it is.
Older batteries such as Ni-MH should be completely worked out from full to dead in order to keep them going in the long run. Li-ion doesn't need to be worked out, in fact the more it is worked out the faster it will run through it's lifespan and stop holding a charge.
Now that batteries, phones, and chargers are all smart, it's supposedly good to keep them plugged in as often as you can instead of letting them run dry.

The post (#7) above is correct on this. You should not let the battery dip below 30%, since discharging it too low may prevent it from being able to take a charge. It happens to most of us on accident every once in a while. But you should avoid it if possible.
It is good to run through a couple charge/discharge cycles to calibrate the battery meter. Many people still think this is to "condition" the battery, but battery conditioning is only the case with the older NiCad type of rechargeable batteries. Charging/discharging the battery just helps calibrate the battery meter on the phone. For new phones or a new ROM flash, I usually charge the battery to 100%, then let it drain to 30%, and repeat a couple times.

It's also a bad idea to charge a cold Li battery, but I believe that affects lifespan more than charge. For those of us in colder climes, remember to wait for the battery to warm up to room temp before plugging in.
On my DZ I usually get 15~20h of battery life and it's O/C @ 1.4Ghz
3G & wifi : always on
facebook, gmail, emails, news, weather updates each hour
about 1h per day of audio streaming (deezer, Synology DS audio)
1~2h of internet and games per day (baseball superstars, angry birds, psx4droid...)
less than 30min of calls per day and about 20-30 sms...

It depends what you mean by "completely". If you drain the voltage of a LiIon battery too low, you will damage it. But the circuitry of the phone is normally designed that there's a cut-off before you get to this, i.e. "completely" discharging it by running it till the phone turns off will be before this dangerous level, so should be safe.
It's unnecessary though, your phone can tolerate a *lot* more partial discharges/charges than full discharges/charges. If you drain it ten times from 100% to 90% and charge again, then that's roughly equivalent to one whole discharge/charge from 100% to 0% and back again.
As redpoint73 said, the main issues it "training" Android to get the battery calibration right, not conditioning the battery (which only applies to NiMH, NiCad, etc).
Li-Ion batteries are protected from deep discharges in two ways:
1. The Phone, it will stop you from discharging too low.
2. The battery itself. Each Li-Ion battery contains circuitry that stops it from discharging too low.
Basically both have to fail to have you end up with a dead battery -> rarely happens.
Li-Ions take the heaviest duty when charging the top 90-100% charge, charging just that bit stresses the battery more than from 0-80% (ofc 0 not really being 0 ) Note: This only has an effect on battery LIFE, not battery capacity! -> if you keep charging your battery from 90-100% (for example by keeping it plugged in after driving to work, then recharge after driving home, basically always going from 100-90-100 you're really doing your battery a disservice life-cycle wise)
If Li-Ions are not in use for a while they should be stored at around 60-70% charge.
Now as for batteries in Android devices, I'd estimate that most causes of extreme battery drain are due to rampant programs/too many internet accesses.
Everytime you log onto the internet, or change speeds (3G -> Edge-> whatever) you take a lot more power than usual. Try to ensure that all your programs that regularly access the net, do so together (HTC Sense interface tries to do this)
Rampant Programs: Especially services that need to poll the clock a lot, or keep updating their info, keep their FPS high (games) It is for this reason I try to avoid installing a lot of programs at once, and keep it one at a time (especially for system programs) to see if there's a inordinate change in battery life.
Oh and do turn off unneeded things like bluetooth, wifi, and GPS if you don't need them... but thats a given.
Gee typed more than I was planning, just get tired of seeing these threads all over

Sorry but I disagree with that. Have you got any evidence to back that up ? Continually charging the battery from 90% to 100% should be fine and shouldn't shorten its life at all. Chargers will sometimes reduce their charge when the battery is nearly full, and a slower/lesser charge will actually increase its life (I have no idea whether the DZ's charger does this or not).

Coming from the Touch Pro 2 forum, there are somewhat occasional posts by users that discharged their batteries too low, and get stuck in a boot loop. Leaving the battery on the wall charger (USB is not enough) for a long period of time seems to solve the issue in some instances, while others are forced to replace the battery.
As you said, instances of this are relatively rare. I've drained my battery until the phone shuts down plenty of times on accident, with no ill results. But best to play it safe and not do it intentionally.
When you mention the phone prevents the battery from discharging too low, is that the hardware, or the OS? I guess either way, maybe the Desire Z or the Android OS are better at this then Windows Mobile and the Touch Pro 2. But I still wouldn't discharge the battery too low intentionally.
I'm pretty sure on the Touch Pro 2 it was software based (hence actually allowing you to boot before saying "not enough charge" )
I doubt that ANY charger that comes with a phone is anything but a normal "charge till full" charger...

Are you using it pretty heavily? I just got the phone Tuesday, and still playing with it a lot, so I can't comment on battery life yet. But what is your screen brightness set to? If you look at the battery use graph, you will see that the display uses the most power, and with any smartphone, the biggest culprit of short battery life. Turn the brightness as low as you can tolerate for your "average" viewing conditions. Also, be sure you've calibrated the battery meter as I've described in Post #8 above.
A word of caution as far as the Mugen extended battaries: one of the users here did a bunch of battary tests on OEM and different aftermarket brands, on various phones. The Mugen 1800 mAh batteries did not rate any better than the OEM 1400 mAh. Mugen tried to explain away the test results. But judge for yourself.
http://forum.xda-developers.com/showthread.php?t=583927
My screen brightness is just 25 or 45%. And i really don't make it to the end of the day.
I now have setcpu, so that when my screen is off my cpu is running on 300mhz. Think i can make it now through the day.
I use my phone a lot, thats true. But only to view the market or twitter things..
Ow and i don't use live wallpapers...
I think there is a lot to be said for keeping things turned off if you do not use/need them too much.
I leave my phone charging overnight (between 11pm and 6:30am). So when I leave the house in the morning it is fully charged.
I keep Wifi and 3G turned off unless I need to use it and I keep brightness to a minimum - again, only increasing it if I need it.
Normal usage for me would be about 1 hours music listening during my commute to work, a couple of texts a day and about 10mins worth of calls a day.
On top of that about 4 hours worth of data use (both Wifi and 3G) and I usually find I still have over 50% battery life left when I plug it back in around 11pm before going to bed (according to the Mini Info widget).
Granted this is fairly light use compared to some people, but I think if you take the time to control your app usage you should see better performance results!
so I got Need for speed for my Xperia S (great game by the way, would recommend) the only problem is it is un UTTER battery drain, I'm talking rapid draining even having the screen brightness on low. Do you think the battery is getting damaged by my heavy use in this way? I'm charging it to full, playing it for a good hour and then it needs to be recharged so I plug it in.
cheers

How about if I play while the phone is charging, does this affect it in any way, like how with a laptop you should take out the battery if its plugged into the wall to extend the battery's life?

No it wont affect your battery...I have been doing that for the past 10 months

It's a difficult question. From one perspective it's better to keep the phone plugged in because a Li-ion battery has a finite amount of recharging cycles. The worst thing you can do is to completely discharge your battery, then completely charge it again and so on several times. Which is what you've been doing and these are wasted recharge cycles.
But constantly charging your phone will also make it hotter and that combined with an intensive game will make your phone too hot, which might result in some components overheating and a reduced life expectancy.
So I'd advice to keep your phone plugged in if possible, but don't play for hours.
When you compare to laptops, it's indeed better to remove the battery when you're plugged into the wall (keep in mind that the battery doesn't lose its charge though, there's nothing worse for a Li-ion than being completely empty). But there's no phone you can run without a battery so you can't do that . It's also a question of luck. I never remove my laptop's battery and it still easily lasts 2 hours after having it for 2.5 years and using it a LOT (when plugged in mostly). It was just a cheap laptop with a 6 cells battery. Most of my friends that have a laptop that old or older (and also more expensive) can barely keep it charged for more than 10 minutes now.
No,
nowadays you can't damage your battery in any way as I know.
But it is recommended to charge your phone to 100% and turn all notifications off then let it on sleep mode till your Phone is going off by itself.
This doesn't improve the Battery lifetime or something like that but it is recommeded
thanks for the advice everyone
I calibrated my note 8. After charing my note to 100% and used it the next day, then it reach 93%.. then i connect it to a laptop using my original usb cable. then after transfering my files i noticed that my battery reach 100% again even if i only connected it for about 5mins, is it normal? is it the effect of battery calibration? but my battery is still discharging the same way nothing has changed, im just afraid that it might affect my battery in the future
my battery acting funny too lately, do you play games, how much your battery consumption on 3D games ? I get 10-20% down on 10 Minute's of gaming... the most battery consumptive device I ever use, must be something wrong with the battery...
so i have a galaxy note 8 and i have had it for 6 months now and the battery life is just awful i can only usually get 1hour screen time and its already down to 60-70 percent.
i have done every single battery saving trick in the god damn books, i have battery saving on, brightness down, no haptic feedback sound, no motion controls, no sync, no auto updates, no gps, the only thing on my quick toggles are wifi and power saving and rotation on.
i have used juice defender
i have rooted and used titanium backup to debloat everything!
i am using greenify
i have tried everything but it does not seem to be improving
someone help me with this

I'm new here since I bought the device yesterday, but this looks like a general issue...
This thread explains battery saving, some issues that might be related to your case are:
- If you misuse Greenify or any other "battery saving" apps they can actually lead to battery drain
- @gafri1: If "When charging , you must power off until 100%" means that every time you charge you must do it until 100% then it's false. Lithium ion batteries DO NOT have "memory", so charging to 100% or 70% doesn't make any difference. There's this thread that contains a brief explanation and this entire website dedicated to batteries.
As far as your specific problem is concerned, what do your battery stats say?
Better Battery Stats and Wakelock Detector can be used to collect more complete battery stats. They DO NOT SAVE BATTERY, they just tell you what might be draining it. The first step should be to check the built in battery stats in the Settings and then turn to other more sophisticated tools.
Charging issues
OK, had a few instances of odd charging that may be what is happening.
One OEM cable got pinched at the head of the micro USB. Shorting and bad connection. Battery shows charging, but never increasing charge.
Ended up melting the head and heating up the tablet.
Long aftermarket charging cable or extension cord. Some do not have proper pin out... will not charge or show charge. End up having little charge after disconnecting from charger.
I watched, a tablet go from 100% to 90% within 2 minutes and slowly decrease the rate until it leveled at 60%. A false reading of charge state until battery data caught up with battery's true charge.
WiFi only, or connected to cell network? This is a very important detail, since if its on the cell network, the reception in your area can have a HUGE effect on battery drain. In fact, when talking about smartphones, I'd say cell reception is the primary factor behind battery life.
In any case, the battery drain you mention (30-40% drain with 1 hour screen on time) is not awful, although not great either. Especially depending on what you are doing during that screen on time (gaming can be a huge drain, streaming video too, but usually less so). I get maybe 5 hours screen on time if I'm watching Netflix. That with no battery saving, WiFi only Note 8.
Also, make sure Smart Stay is turned off, as it seemed to me to be a big battery drain (and never really worked all that well for me, anyway).

Agree with both these points. I've seen these "battery saver" types of apps (Juice Defender in particular) which have caused more issues than they solve. Some folks will swear by them. But don't take for granted they will increase your battery, and use them wisely. Don't "misuse" them as you say.
And charging while the phone is powered off is a myth that has been debunked long ago. Aside from the fact that the device will charge slightly faster (it won't be draining as its charging) this will have no effect on battery life.
Thx for information
exactly the same for me

I have noticed some cables are faster than others. My bedroom charger will charge from dead in under 3 hours, the downstairs one will take 4 hours.
leave it on power saving mode always. It's the only way I get the battery to last on idle. in comparison the ipad air can sit days / weeks almost on idle.
Does battery lfie improve with CM? Can we put CM on 4.4 kitkat note 8?
My H815 had started reporting strange battery stats. I took it off charge an hour ago, but the battery stats (in Settings) say that the "Usage on battery" is 23 hours. The battery has also started charging more slowly, and discharging more quickly, recently. Does all of this suggest that the battery needs to be replaced?
Not necessarily. I would try a battery calibration and maybe even a factory reset because
itm said:

doesn't fit. Usually batteries on their way to dying discharge *and charge* faster.
Also the report that it's on charger while not, may indicate a software or even hardware problem.
How old?
About 1 year old. I've noticed that it is drawing a lower charging current when connected to the Quick Charge charger (less than 500mA). It used to draw 1000mA+. Also, my car charger no longer keeps it charged when Google Maps is running - i.e. the phone discharges more quickly than the charger charges it.
What's the best way of re-calibrating the battery?
Run it totally empty doing something intensive. When the phone shuts down, wait some time, then power it on again and try to use every last drop of energy. Maybe do this one more time. Just make sure there's nothing left.
(That's the manual way of discharging. There are also apps available that will turn everything on and discharge your battery very fast. But some say they are bad for the battery.)
Then charge to 100% preferably with the phone powered off.

Thanks. So discharging it to the "Low Battery" warning (15%) then recharging to 100% is the correct thing to do?
Well I would say not everything is fixed and absolute.
For example, you also shouldn't charge to 100%.
But, battery and chip manufacturers incorporate this into their designs, so 0% and 100% are not really that, in order to protect the battery, and give the people an easy life. For example, instead of suggesting everyone to remember and stop charging at around 90%, they make the chips report 100% when they're about 90%. The same is also true for 0%.
I would say discharge fully. The low battery warning is a warning for you to not be left without energy when you might need it, not to protect the battery. The internal chips handle that. 0% is not really 0%.
Edit: in the link I provided in my previous post, check figure 3. Among others, you can see in the data provided by a battery "Absolute state of charge" and "Relative state of charge". That's what I'm talking about. We users see the (protective) relative state of charge, not the absolute.

It's difficult for me to write all in English, sorry. Don't wanna to be vague, linked that site only because I know and read it and I like very much what they say.
I think to discharge battery to the lowest possible isn't a good work, even with the relative % indication. For a simple calibration of a li-ion battery I think it's ok to discharge till phone power off then recharge full. Calibration has nothing to do with battery cycle, it's only software problem. The phone has to calibrate % on true capacity of a wear battery.
Discharge, power on, discharge again, power on, discharge even the last drop of energy isn't a good practice in my honest opinion.

So we agree. Because we are talking about calibration here.
Every day usage is a totally different story. A li-ion battery should not be left to go below ~40%. Also, slow charging is better than fast (you can imagine what this means in relation to Quick Charge and related technologies. Don't use them if you have the time)
But the question was about calibrating.
Yes, we agree, but before you're talking about discharging every single drop of energy from battery to calibrating it. It's that what I mention not to do, it's a bad practice for li-ion battery, even with security chip, and all that for a simple calibration issue. Just my two cents ✌?
