Battery settings,

Can someone help me out here this is for an Orbit 2 less than 1 week old. I charged the device this morning so by 09:00 it was on full power. By 14:00 its down to 75%. Usage below:
10 minutes phone calls
I have my email set to retrieve from Yahoo every 15 minutes
On battery the screen is set to 50% - 75% brightness
Co-pilot has live function and traffic updates, but I presume that is only when its actually turned on and running Co-Pilot
What is going wrong?

Firstly, did you give it 3 charges of 16 hours plus? I didn't, and don't have as good a battery life of some others that did.
Also, have you got Windows Live connected and checking your hotmail constantly? That killed my battery.
Finally, I leave HSDPA switched off, as I find it chews juice without being THAT much faster; 3G is fast enough browsing and downloading for me.
Good luck, keep us posted.

I've got a HTC TyTN (hermes) and i get the same problem: my battery wears off in maximum 3 hours after i fully charge it. all the connections are turned off,except for the phone function. also, while it's charging, no matter if it's charging through the usb or the AC charger, the battery gets very hot. PLEASE can anyone help
(i have the black satin normal rom, with the 1.43.00.00 radio version installed)

I all so have battery questions. This devise was advertised as an 7 hour talk time on GSM. Compare to my T-Mobile wing witch was only 5 hour talk time.
I don't use phone a lot during day only 5-10 min phone calls and every 60 min e-mail check. And T-mobile Wing (p4350) was going for 3 days no charge no problem. And This I have to charge every day. At the end of the day i have only 60% And T-Mobile USA don't have 3G eat.
I don't get it this phone supposed have one of the best battery life out of HTC phones. And I did charge it wan i first got it for long time before i tern it on.

About chargin and discharge our phones, whe have to remember that we do not use NiCd/NiMh batteries any more.
I have some facts about Li-ion batteries!!!
Guidelines for prolonging Li-ion battery life!
Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a long time, they should be brought to a charge level of around 40% - 60%.
Lithium-ion batteries should not be frequently fully discharged and recharged ("deep-cycled") like Ni-Cd batteries, but this is necessary after about every 30th recharge to recalibrate any external electronic "fuel gauge" (e.g. State Of Charge meter). This prevents the fuel gauge from showing an incorrect battery charge.
Lithium-ion batteries should never be depleted to below their minimum voltage, 2.4v to 3.0v per cell.
Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator. Aging will take its toll much faster at high temperatures. The high temperatures found in cars cause lithium-ion batteries to degrade rapidly.
According to one book,[35] lithium-ion batteries should not be frozen (most lithium-ion battery electrolytes freeze at approximately −40 °C; however, this is much colder than the lowest temperature reached by household freezers).
Li-ion batteries should be bought only when needed, because the aging process begins as soon as the battery is manufactured.[13]
When using a notebook computer running from fixed line power over extended periods, the battery should be removed, and stored in a cool place so that it is not affected by the heat produced by the computer.

16 hours?!?!?!!?

It's a highly debated point, but it seems some who have done the old "3 charges of 16 hours" have a longer lasting battery than certainly I do.
In fact the O2 shop I bought the phone from advised the same, although I didn't actually do it!
Who knows the real best thing to do, all I know is I only get a day out of it, with light to medium use and HSDPA turned off.

Personally, I'm a little speculative of the 16 hour charge times.
I'm not gonna try to be an expert here, but aren't Li-Ion charge circuits designed such that when the battery reaches capacity, the charge cycle is complete? Ie. There is no further trickle charge to the battery? In that case, the 16 hour charge is not doing any good.
But in any case, I myself get 2 days fairly easily with about 1.5-2 hours of phone calls in an Edge area.
I am a firm believer a big difference comes from using of Standby and your signal strength. I've noticed where I go ski'in there is a very weak signal and my battery life drops to 40% or less in one day. So I think this is one major characteristic that will vary between all of us and will dramatically affect the battery life test results.

DaRacerz, you are absolutly right!
No trickle charge is applied because the Li-ion is unable to absorb overcharge. Trickle charge could cause plating of metallic lithium, a condition that renders the cell unstable.
So charging for 16 hours won't do anything.

Serious battery capacity decrease

Hi, I just ran powercfg /batteryreport in CMD. The generated report states that after 30 charge cycles, my full charge capacity has dropped to 27,646mWh. the designed capacity is 31,502mWh, so my battery lost 12% of capacity in just 2 month!!
does your surface also suffer from serious battery capacity decrease? please run "powercfg /batteryreport" in non-elevated CMD and look at the report in C:\Users\*username* please post your result including full charge capacity and charge cycles.
Thanks!

mine is unchanged, reporting 16 cycles. I got the Surface 12/17 so I'm a week shy of two months myself.
I don't let my LiOn batteries deep cycle (drain down past 20%) if at all possible, as this reduces their lifespan.

Yeah my battery report says the same thing, even though I haven't noticed any lifespan decrease yet.

Mine has also dropped from 31,502 to 30,444 and 3 power cycles. Surely the battery can't be degrading already?!

At 34 cycles, mine has settled from 31.502 Wh to 30.214 Wh. It is very slowly losing capacity still (was at 30.740 for a few weeks in January) but seems to be mostly holding steady. The noticeable drops correspond to deep discharge cycles; I'll endeavour to avoid those.

Mines at 28472 with 38 charges. I got mine at launch 10/26/12. This is scaring me. Coincidentally I have noticed a decrease in battery life and was wondering if it had to do with the jailbreak as that is when I started noticing it.

47th cycle now, I still have 30,281mWh. I got my Surface RT at around 25th Dec.

29,415 after 47 cycles. Pre-ordered mine, arrived around launch date. This does seem very weird, batteries really shouldn't do that. Anyone have any experience with getting one replaced? Hopefully this isn't a problem Microsoft wont acknowledge.

cant seem to find my stats.. it only says mwh without numbers.. what the hell?

Mine seems to be worst here. After 24 cycle count, I'm down to 26,729. I do let the battery drain all the way - may be that's my problem.
I've had my Surface since Oct of last year.

That might be the issue perhaps, I have never allowed my battery to drain 100% or 100% charged for too long.
Mine is still at 30k range despite 49th cycle

I am extremely upset about this - in only 25 cycles, my battery capacity has gone from 31,502mWh down to 24,154mWh. And to top it off, I have been wondering why it seems the battery life isnt that good anymore. Is this permanent, or can you condition your battery by not allowing it to drain as much?
I have been letting it drain all the way down, and when i charge it, i plug it in overnight. Obviously this is the wrong way, WTF - you would think that they would tell you about this in manual, etc.

To be fair, this has been common knowledge for literally as long as laptops have been using Li-Ion batteries (well over a decade). I agree that it should perhaps be better documented for those who have somehow never before encountered a LiIon battery, but acting like this is some never-before-heard-of consequence of hard-draining your battery is... weird.
Leaving it plugged in all night is fine; the charger is pretty smart about handling that. Just try not to let the charge level drop below 10% (ideally, not below 20%, just for some safety margin) and you should be fine.

The charging system is smart enough to not overcharge, so you don't need to worry about this.
No one should be "reconditioning" or deep cycling batteries anymore - at least not if they are LiOn/LiPoly.

Got mine 11/4, 22 cycles, down to 25,xxx. Pretty disappointing considering I don't let it die all of the way. I'm hoping this is just an OS reading issue.

I turned off all low battery alerts and forced the battery to run completely dead, and recharged, and now mine has gone up a few points to 28,579 from 28472, with 39 charges, so I think it needs to be reset once in awhile. I however was not aware that leaving it to charge all night and using while plugged in could hurt the battery as others said - Still question that logic. I also have used it to the point of turning off but because Win8 has adjustible power options to force it to turn off when it reaches a certain battery level, I am not sure any of us run the battery down to nothing.
i just wish we could get a stupid battery ap/utility that would tell us battery life left in percentage or something to help us monitor it better.

+ 1000

Got mine on release, I've fully discharges mine about 3 or 4 time mistakenly, cycle count 49, full charge capacity 29,985, given this I've altered my battery plan to give a warning (low battery level) at 20% rather than 6% and to shut down (critical level) at 15% rather than 3%.
Oddly enough, my battery plan has never been adjusted so theoretically it should never drop below 3% yet my battery report clearly identifies it dropping to 1% at one point.

So, are you guys telling me that I should try letting it drain down to 0 and then recharging it to see if it is simply an issue with calibration?

Battery problems

I own an Orange Neva 80(rebranded ZTE Blade v7) and I recently started having some battery problems. Just 2 days ago I was stunned by the fact that it took about 2 hours for my phone to go from 90%+ to 0%, which is an unusually short amount of time. The top part of the back of the phone also seems to heat up pretty easily. I downloaded some battery apps from the store and I noticed that when my battery level is about 90% the app says my battery only stored about 1000mAh, so less than half of its maximum capacity which is 2500mAh. The phone is only 1 year old and I expected the battery to last longer than this. Is replacing the battery the only option or can something be done to save the current one?

- Smartphone batteries are usually designed to last for about an year or year and a half; specifically speaking, that is around 300-500 charging cycles. However, majorly depending on your charging habits, your battery can have more than 300-500 charging cycles lifespan. Meaning, every time you plug in your phone to charge, it uses up a charge cycle.
Answering your question -
Before you purchase a new battery, find out why your battery is draining rapidly (Besides the fact that it is operating passed its charging cycles capacity):
1) Issues and fixes:

2) Try re-calibrating your battery: https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device
If everything fails, time to replace the old boy.

Anyone using the AccuBattery app?

What battery health does it report for you?
https://play.google.com/store/apps/details?id=com.digibites.accubattery
Had my Pixel 2 since Nov and tend to try and look after the battery with the now popular wisdom of not charging beyond about 80% when I don't need to. AccuBattery already now reporting 87% battery capacity (2362mAh total), even when benchmarking 0-100% charge. I can't recall what it reported when I first used AccuBattery - maybe mid 90's?
So perhaps I have a low capacity battery, or maybe AccuBattery should not be trusted anyway. Most users seem to get good and believable results from it. In use the Pixel's battery life seems reasonable and consistent with what many folk see, but we're only talking about a 13% margin and usage models and thus battery life change much more than that from person to person. It's just a 13% of extra capacity/life between charges that I'd quite like to have!
But how on earth do I prove reduced/poor battery capacity to get a RMA? I can't say "an app on the Play Store claimed XYZ". Phone was purchased from Google. Maybe I have to RMA based on some other fault I can cite that I can prove?!
Any ideas/experience of any of this?

I've had my pixel 1 for about 5 months (I got a warranty replacement because my previous battery would die in half a day), and AccuBattery shows my battery capacity health at 2087 mAH

My original Pixel 2 actually and genuinely stopped charging intermittently and I had no trouble getting it RMA'd. AccuBattery performs the same on the replacement.
I have now found with my Pixel 2 that AccuBattery under-reports capacity almost always whenever the phone is partially charged. It reports higher capacity when the phone is fully charged - the state it gets to beyond a reported 100% and when it actually stops charging. I put this down to a non-linear battery gauge on the phone - probably by design

I've had mine since October, never bothered with anything fussy like stopping charging at 80%, mostly used the supplied (fast) charger overnight (occasionally other chargers/power banks/USB). Today it's saying my capacity is 93%, but yesterday it was 89% and a few days ago it was 85%. The main thing I take from that is that it fluctuates by several % day to day.
Anyway I'd be amazed if they accepted 13% battery wear over 11 months usage as grounds for an RMA.

I asked this exact thing on Reddit and got nowhere. It's got to be some issue with pie and accubattery. All three of my pixel phones suddenly lost 15-25% battery capacity after pie. 2 pixel 2 and one og pixel XL. Right after a factory reset my pixel 2 shows 99% capacity and then slowly drains down after some charge drain cycles . Perviously it was always above 95%

Samsung S7 - Abnormal battery wear

Hello,
Sometime ago I started to notice battery in my S7 is much weaker than at the beginning. I checked how it works with cleaned system but effect was very similar. Then I installed two apps to check battery wear:
-Samsung Phone INFO: https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
-AccuBattery: https://play.google.com/store/apps/details?id=com.digibites.accubattery
Effect was very similar: according to Phone INFO battery had around 370 charging cycles and it had 76% of new battery capacity. For me this wear wasn't normal. Battery was replaced under warranty.
Now I monitor battery again. Phone INFO noticed 12 charging cycles (AccuBattery shows 28 cycles because it also notices charging between 40-80%) and wear is similar in both apps: 95% left.
I wonder if you would be able to check battery wear in your S7 mobiles and let me know how it looks in this thread? My warranty expires in 2 months and if there is anything wrong with motherboard rather than battery itself I would try to sort it out.
In app https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo there is tab Personal and there are two important for me fileds: "Battery Discharge Cycles" and "Battery Health"
Thank you in advance

My 2-years old S7:
Cycles: 513
Health: 84.7

Results from AccuBattery
Mine, after 2years and 2 months:
2.353mAh average.
I assume that would be 78% health. (2353/3000mAh)
EDIT: Where can I see my charge cycles? I will post them when i find them.
