I know this crazy question but here goes. I am doing the battery thing where you need to drain your battery until the phone shuts down. What things can I turn on to get my Battery Drain FAST? I told you it crazy.
Thanks
Turn on wifi, Bluetooth and turn ur brightness all the way up. Also turn on gas and then run a background that moves.

Thanks. I had phone at 35% and wanted to try to drain completely so I could Charge overnight.
Turn screen on full brightness and play angry birds while streaming music from Pandora at full volume.
Curious why you would want to drain fully just so you could charge overnight?
When you drain the battery and then recharge it completely, it helps increase the volume of the battery to help it last longer.
huh? I think you need to do some research on li-ion batteries.
I think.he might be trying to recalibrate his battery
I kinda thought that but the post regarding increasing capacity of the battery threw me.
it won't be XDA without ways to magically improve your battery life.

I'm pretty sure he was referring to calibration increasing phone uptime and accuracy of the battery meter, rather than actually increasing the battery's capacity.
Yes that's what I was trying to say. not the best at explaining

I recently installed Serendipity and made sure the battery was at 100% while doing so (and deleted the battery file). I'm waiting for the battery to drain before I plug it in. Am i supposed to let it charge all the way again? Also, is it safe to reboot the phone while it is draining the first time? I want to install something using clockwork.
I'm being careful about this because cognition would report 14% battery life after 33 minutes of display usage and display eating up 96% of my battery....

There's a complete thread on this, I suggest you look it up.
After you reset your battery stats, it is suggested to do a few full battery circle (use til dead, full charge, rince and repeat). You should be fine after 2-3 circles.
Note tho that it will not improve your battery life. All it does is a attempt to tell your phone what % your battery life is exactly.
For your fast drain, I don't think it has anything to do with your battery calibration or your ROM. It's most likely a app (or a few) that are draining alot of juice or that are running w/o realy being needed. (Check your running services.. make sure you know which one to stop and not to***)
Also using a app/widget like advanced task killer can help your battery life as it will stop every app running with a simple touch. I suggest doing it anything you're not using your phone.
One last thing, display eating 96% of your battery is normal.. it's not telling you it's using 96% of your battery. It's telling you that during the time your phone as been unplugged, your display use was your main action.. probably cause you didn't make many calls or anything else.. Display is just about everything you do with your phone so it will always have some high numbers like that.

Yeah, I've seen the thread before but forgot about it. Thanks for reminding me. And my point about the display was that it was on for such a short amount of time, yet still killing my battery.
I am now down to 30% or so after 3 hours or more of display time after calibration & rom switch- and I was streaming music through WiFi and using Bluetooth headphones. So it it seems like it made a huge difference =D
Thanks
What is the best way to swap batteries with different capacity?
I noticed then when you put a new one it retains the old %. Wiping the battery stats helped a little but the reading is still incorrect because the phone stayed on web surfing in 3g for 30m with 1% which is impossible.
Also what app can I use to test the battery duration? like a stress tool that does the same thing in cycles so I can see which battery lasts more.
Just use the phone normally, after a few charging cycles the readings will match the actual %. Wiping battery stats doesn't really help, as it is not really related to reading the battery's state as some people used to believe.
Use the Battery Drain app by Waza_Be found in Google Play. It records the time every 1% decrease, letting you to know how long 1% of your battery lasts
Like silentmelodies said,
this will settle with your battery being fully charged a few more times.
I am using battery calibration app everytime I install a new rom.
It doesn't work The indicator is stuck at the previous level
Leave the battery out for at least 15 seconds before inserting the new battery. Then you'll get the correct reading. Don't be quick ;-)

Yep, what I also do is tap the power button to clear any residual charge, seems to allow me to change batteries faster.
its bad practice, but I pull the battery out with the phone on, but screen off. the new battery will show the correct percentage...

Hey guys
I have problem with battery
Now my battery 40% when left note sleep up to 3h i back i see battery 41%
I saw it with custom roms and stock i tried all kernels
And problems sometimes appear and sometimes no i tried wipe battery and
No diffrent
I want to destroy this problem for ever
Thanks alot.
No One Know How i can fix it ?
I don't think it's a bug.
I'm pretty sure it's just the way it estimates your battery percentage.
Here's how I think it works.
If you've been using your phone for, say, 3 hours straight, your phone calculates your drain rate like batt%/min or something.
And judging by how long you've used it for, it will estimate the approximate percentage of battery remaining.
When it's on deep sleep for a while, not only is the clock rate different (probably <200mHz at deep sleep), but the drain rate will change too.
The phone will re-estimate the battery percentage according to that new rate, hence the different (often higher) battery percentage, after a period of inactivity.
I could be completely wrong, but that's how I see it.
Thanks for ur Idea Brother
Any one have other Idea ?

If Battery drain is your problem, try this-
Discharge your battery till it switch off automatically
Now connect your charger in switch off mode and charge it till the full.
Now after recharging it fully, unplug your charger from the socket.
Go to recovery mode and go to advance,wipe battery stats and restart your device.
HIT THANKS BUTTON,AS IT IS MANDATORY.

Brother my Battery Not Drain its Incrase 1% with itself on deep sleep
Just as the title says is the power saver options like CPU and data connection really useful as well as the "sleep mode" option in power settings or are they making battery life worse?
If they are power savings options i don't see any reason why it would drain even more?

well according to this quote from another thread on xda in the sprint htc one forum,so I wasn't sure because it says it does make it worse.
"Power Saver mode will not save you any remarkable amount of battery unless you are maxing out the CPU or GPU (like playing games). Since what it does under the cover (besides what it advertises in the options) is downclock the CPU, this can actually be a detriment to battery life. It is better for battery life for the CPU to run at max speed for very short periods, and then go to sleep. It uses more power by running slower (and thus staying awake longer)."

Anyone?
I keep the power saver on most of the time. The main things I notice is that it dims the display (not really an issue if you work indoors) and it disables the wifi and data connections after periods of inactivity.
No real downsides (I'd be curious to hear other people's experiences). Sometimes receiving WhatsApp messages takes a couple extra minutes if the data/wifi connection goes to sleep.
Seems to give me good battery life - I average 15-18 hours, and that's including a fair amount of on-screen time and music/podcasts during the day.
I used power saver quite a bit in the 2 months after I got the phone but I don't use it anymore. In my experience it helped very little (as in added an hour or 2 maybe to overall life per charge). My baseline average battery life is 21hrs GSam tells me, and that's without power saver on at all (wifi, nfc, cellular always on and screen at 100%) and about 3hrs screen on time.
It may just be that, as was mentioned above, my use doesn't utilize the benefits of power saver because I don't often do cpu intensive things. It did run a bit cooler though. I also prevented the mode from diming the screen. I always (and still do) found that most of my power was going to the system (apps etc) @80% even with the screen maxed, and that I would lose about 20% overnight with our without power saver. So I stopped using it because : 1. It didn't improve MY USE 2. I didn't like the notification icon 3. I hear really good things about Battery Guru from experienced XDAers and the app seems more intelligent than power saver to me so I use that now. Unfortunately it's still too early to tell how much this will increase my average usage.
Regarding the issue of damaging your battery, the way it was brought up refers to the number of charge - discharge cycles a battery has. So only something that discharges the battery more quickly (so that you have to do another charge cycle more quickly) will shorten the battery's life. If nothing else, logically using power saver would not do this. It won't hurt the battery and may not hurt your usage (remember the GPU can still run at full clock for games), but I don't think it will help you much either based on my experience.

dont believe everything you see online. All it does it limit the CPU, as opposed to running 1700mhz, its capped at 1134mhz, this is not detrimental.
it takes power to make power, undervolting and downclocking processors has been repeatedly proven to assist and aid battery life.
it takes a certain balance or the two to get great results. Mind you the stock kernel is great but its adaptive. So dont be discouraged when seeing bad battery life initially.
If I leave my phone off charge overnight, I usually loose around 5%. If I turn powersaver on, I only loose 1-2%. This is with around 8-10 hours of no usage, with wifi on. It also turns off vibration feedback when using the back and home keys.
I've also noticed the phone to be slightly less responsive with power saver on. As far as I can tell, if you are concerned whether your battery will last you the few more hours you need, it will definitely help save power
It makes a difference and if you need the extra juice it will help you.
However, the amount of difference depends on your use.
If I am using Snapdragon Battery Guru should I deactivate Power Saver? Is the Power Saver a better/worse solution or a complementary one for optimising battery life?

Theoretically they should work together fine because Battery Guru studies what you do with your phone so that it can figure out what to prioritize and what to shut down - it adapts so it should adapt to the power saver situation. Underclocking the cpu shouldn't change what services it adjusts because you're still doing all the same things.
Battery Guru just finished "learning" on my phone yesterday so I don't know how good it is. But I lost 40% overnight for some reason which has never happened before. It's probably still adapting. Life seems to be better during use...
The comment above about the OS being adaptive is also very true, my first few charge cycles were dismal but they got better within a week (without power saver etc.)

Ya I'm using Juice Defender Plus on my HTC one running 4.1.2 for a few months now and I'm not sure if it's making too much of difference. Are you finding Battery Curu pretty decent?
I turned it off on my wife's HTC One. It was disabling data/wifi after several minutes inactivity, which caused FB Messenger to freak out and stay awake, which caused the battery to drain faster than if the data was just left on.

Sorry still to early to tell really, it's learning period ended yesterday so it'll take time for GSam to find the new average usage. But again it SEEMS to have improved drain during use. I'm really not sure what the drain last night was but if it happens again tonight the app is gone...

I used to have a higher drain, but after some research, I found out using betterbatterystats that google maps was waking up the phone often and preventing sleep. I corrected this by disabling "report from this device" in google maps settings.
Before this, I experienced similar battery drain with power saver on.
From experience, it's best to determine phone sleep time and app battery usage, and correct this to achieve the best life.
I'm currently able to get two days with light usage without power saver!

I changed my mind, I'm consistently losing 40% per night after Battery Guru activated. I can't confirm that this app is the problem, but it's never happened before and I haven't changed anything but adding the app. Maybe just me experience though.
Sent from my HTC One using xda app-developers app
I've uninstalled BatteryGuru for the same reason
I'm relatively certain that for many people this is super old news, but I'd like to share this anyway just in case it helps anyone (and a bit because I'm just so impressed by how it works )
I've tried a few different power saving strategies on this phone and have been disappointed with all, including just keeping power saver on all the time. I would always lose 20-40% overnight no matter what I did. I should also clarify that it is not acceptable for me to just disable a bunch of things to get that drain under control. So one day I turned on power saver (everything checked off) and just turned off wifi, and I've been doing it ever since because now I only lose 5-10% over night maybe a strange thing to be excited about considering my other devices lose as little as 1% in that time with nothing turned off, but everything's relative.
I think now I'll try keeping wifi off and power saver on throughout the day and see what I get. Though I'm not sure I like the thought of data being turned off during the day when the screen isn't on...
For me at least this is the single best battery saving thing I've ever done on my One.
Sent from my HTC One using xda app-developers app
What you mean by saying that you "turned on power saver (everything checked off)"? What Power Saver does if everything is checked off? I suppose like that it actually doing nothing. If you uncheck everything and turn it on isn't the same as turning Power Saver off?
After charging my battery fully to 100%, I unplug it from the charger and without even turning the screen on, the battery drains to 92% within one hour. I check the battery stats and there are maybe only a couple wakes during this time.
Sometimes, the battery shows a certain percentage longer than others. Example, my phone will be on 65% longer than it would be on 60%.
Battery still gives me a solid 2 days usage with about 3+ hours screen on time. The service menu also says that the battery is good.
Is there a way to get the battery reading to show more accurately?
Thanks,
Hope I could Help You
For your battery problem, I guess you could try calibrating it. And also try to install "Greenify" along with "Clean Master or 360 Security" and try to close all running apps before turning off the screen. I also turn on Stamina Mode when the battery is at 100%, in an attempt to further save battery life. And the result has been kinda meh, but well, battery drains about 1% per hour. It lasts about a day and half with light usage. In my case, light usage being, browsing, youtube videos for about 2 hours, listening to music, social networking and taking some pictures

Hey,
im using greenify (my phone is rooted). Battery is quite good for me though. I get about 3 days with light usage. I start charging my phone again when the battery gets to anywhere between 10-20%.
I read that maybe its better not to let it get so low?
I have no wake locks either.
Umm.. IMO, 10-20% is okay. I usually charge the phone when the battery gets around 5%. I read somewhere that charging battery too early can affect the battery's overall standby time (reducing it). It's better not to let the battery reach 0% though.
I had that happen with my Samsung Galaxy Note 2 earlier. I once let the battery dip all the way to 0% many times. After a few charge cycles, I found out that the battery was dead and wouldn't charge at all so I ended up buying a new battery :-/
Umm.. Coming back to our Z1's, could you try putting the phone in stamina mode everytime the phone is kept on standby mode? This boosted my battery life a lot I even put my phone on stamina mode throughout the whole night yesterday to test the battery life again, and when I switched on in the morning, I saw that the battery had dipped by just 2% (standby time of 7 hours). I'm really confused how your battery drops so fast, 100% to 92%.
Could you try calibrating the battery and then putting it in Stamina Mode while on Stanby and tell me the results? I hope I could help :fingers-crossed:
