No matter how many times I calibrate my battery, it lasts for over 30 mins of straight youtube watching with 3g wifi bluetooth and gps on. I know there's no need to calibrate after the stat wiping after charging to 100% but I would like my battery to display correctly. The past two calibrations told me it was off by 8% but it did it twice not only once. So how can I get my battery to display correctly and not last forever sitting at 1%

Charge to 100% (leave on charger for 4-6 hours) then calibrate (remove batterystats.bin) then deplete battery until phone shuts off by itself, then charge without break to 100%.

There is no battery calibration. A google engineer has already ended that theory. The batterystats.bin updates everytime the phone is plugged in to charge. Dropping your battery to below 20% before charging is always a wise decision, but you can't calibrate it by deleting file.

I already stated that above but my phone can sit at 1% forever and not die so somethings obviously off

Obviously it's your battery.
The phone gets the %charge by the voltage. A good battery has a linear drop of voltage during use, but if a cell is defective, it can report a misleading voltage drop curve while still having enough charge to work. IF the battery drops under a determined voltage AND current, it shuts off. While both conditions aren't met, the phone keeps using it until a safe point, where it doesn't damage circuits or the battery itself

Guys, i have this problem where the phone shows a popup message - "Charging paused.battery temperature too high or to low".
It generally occurs when i CHARGE my phone with 3G DATA and WIFI hotspot on.When i check the battery temp, it shows 60 degrees celsius, and the battery HEALTH is good.
I then have to wait sometime to let it cool down to about 40-50 degrees before plugging it again.
I just want to know if using my phone before the battery is cold enough will damage it our not?
P.S - I run stock gingerbread, no root.

If you continue charging at that temperature or use too many apps while charging, battery capacity will decrease over time due to the extra heat. Its always safer and more beneficial to charge the battery when it isn't warm , to ensure its better longevity.
It's better if you off 3g and wifi during charging as it could reduce battery power.
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.

Hmm... If I leave my phone off the charger overnight after a full charge with power saver with WiFi on for 6 hours it will be down to 95% with no usage.

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.

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?
Hey.
I bought à New battery three days ago. First Day, battery life was really great.
But yesterday and today, not great.
I think I should make à battery calibration but lots of personns aren't agree with the Best method and I can't let my Juice to 0% because it can be responsable of battery life lost (20%).
So anyone can explain to me please ?
Thanks

I think that li-ion battery cannot be calibrated. All that you could do is to ensure that you use it properly for about 3 cycles, meaning good full charge without interuption, and discharge until your phone turns off. (Do not turn the phone on until you connect charger, but it seems like you already know that). This should ensure that your battery is performing as best as it can, and that the phone is displaying battery level correctly, without sudden drops.

Thanks but the problem is to let the phone discharge completely, can be lead to lost 20% of autonomy people says.
So I don't want to damage my new battery.
Idea is to let your phone shutdown due to no power, not to drain battery completely.
Battery fakes "no more juice" status when it is nearly dry and phone shuts down due to that.
As long as you do not boot it up after it shutdown on its own (it will allow boot with like 1-2% battery even when it said 0% - shutdown) it is all good.

You shouldn't discharge your battery to 0% every time, but some batteries, especially non-original ones, need formatting in first couple charge-discharge cycles. By formatting I mean complete charge to full discharge, usually 3-5 times. Before formatting you can reset battery stats.
After formatting you shouldn't discharge battery under 15% too often. There is no harm in discharging it below that level from time to time (some suppliers even advise doing full cycle once a month).
If you want to maximize every li-ion battery life you shouldn't discharge under 15% and charge over 80-85%, but it is impractical and you won't use this phone after a year or two so don't bother yourself with upper limit.

I have Z3 Play for few days now and I was thinking it's great that it has battery mod included. I see it's working in quite stupid way. In efficiency mode it keeps battery at 80% but not in a way of using battery mod for powering phone, but charging phone very often when its charge drops little bit. I think that is good way to kill internal battery.
Other option is just turning on to charge internal battery when it gets low, but that is also not a way to prolong internals battery life. Battery mod seems totally useless for me.
So I'm wondering is there any way to change how battery mod delivers it's power to the phone?

The only way I knew it from Oreo that you can force the battery mood to stop charging and activate it again upon your need.
