Just want to share my experience of 'best' charging method that can maximize the battery life of my Nexus one.
Firstly, let me introduce my equip:
- Machine: Nexus one
- Rom: FRF91 Stock, Deodexed, rooted, busybox... (Geo411m)
- Kernel: intersectRaven's 2.6.35_AVS-925mV_CFS_20100802_1056.zip
- Control: SetCPU, Interactive: 245-960Mhz when on, and 245-245 when screen off
The key method of obtaining max. battery life is the 'GOLDEN' time from 100% drop down to 99%. Once the battery shows dropping from 100 to 99%, the dropping speed is quite stably fast onwards
So, how to retain 100% longer before dropping to 99%? Below are the steps that really work for me:
1) Charge the phone to green light, some where between 90% and 100% (say: 95%)
2) Disconnect USB charging cable
3) Turn off the phone
4) Connect USB charging cable and charge the phone, it should show orange light
5) Set a timer, remember to *ONLY charge the phone for around 20-25mins*
6) The concept is NOT to charge the phone until you get green light. In order words, you need to charge the phone from 95% for 20-25mins where the light is kept ORANGE with the phone turned off!!!
7) After 20-25mins, disconnect USB cable and power on your nexus phone
8) You are done and the battery should last longer before dropping to 99%
9) Time in step (5) depends, you need to trial-&-error
For my experience, I normally charge the phone before I sleep and disconnect the charger. In the morning when I get up, it usually shows around 95% of battery. Then, I power off the phone and charge it. And then I take breakfast, bla bla bla ~ and after around 20mins, disconnect the charger and go to work. The battery can retain 100% for around 30mins of continuous web browsing, facebooking... and when I reach my office, sometimes, the battery still shows 100% !!!
So, above is my experience of how to maximize the 100% retaining time.
Please feel free to try and share with us whether it really works for you
Great advice.
Personally, I can't really be bothered with going out of my way to be overly concerned about battery life. I don't play games on my phone -- that will change when Angry Birds is released for Android -- nor do I watch movies, and I don't really do too much web browsing. Sometimes I listen to music, but not often.
I can go 12-14 hours of normal use (mostly Twitter and text messaging) and that will put me around 45-50%. I'm never somewhere that I can't charge the phone if I need to; USB at work, regular charge at home, and a charger in the car.
All of these tips and tricks for extending battery life are neat, but why bother?
^ Well looking at your usage, and the plenty charging points, of course you dont care. However, some ppl browse a lot, play games, so every last inch of battery life means something.
I just keep spare batteries in my pockets =D
I will try your golden tips.. then I will write my thoughts.
I thank you for sharing.
Screwing up the battery meter does not get you more battery life, period, and I suspect your shenanigans here is doing that. The battery has a set capacity, it's not going to charge more than that.
The Nexus One and a lot of other modern phones with modern batteries DO NOT trickle charge, they charge to 100% and STOP charging. When the phone drops to a certain limit, it charges more. Repeat as long as it's on the charger. This is why you might see it "drop a few percent" when you pull the charger.
Yea this sounds like a huge placebo effect.
Well I just did this, been off charger for over an hour.. still 100% after over an hour and two reboots.
At 1378mAh right now, didn't get a reading straight after first reboot unfortunately.
I'm also trialing autorun killer. Disabled a free services I don't use.. seemingly increased startup time.
heya,
Don't you mean decreased startup time?

Yeah, that's what I mean.

How do you figure out your mAh level? Spare parts only shows me mV.

This is placebo. In the OP you even say after it finally drops to 99% it drops fast after that. It's because the phone wasn't at 100% all that time. It was giving you a false reading from messing with the charging pattern.
The best way I've found to charge the phone is to delete the battery stats, turn the phone off, and charge it until it's green. I get a great day of battery life with the phone that way.

Totally agree...I just charge when & where necessary and never worry about it! Don't have the time and it seems to last long enough for me to work & play
I had already discovered this and was looking for a fool proof way but I guess you beat me to it. Happens when you traveling alot. For me, I have gotten over 1500mAh more than once..some times 100% would last me half a day too. So it's worth it, my question is whether or not this is bad for your battery? or long term battery life.

I'm fairly sure that the Milliampere-hour (mAh) is the capacity of the battery (the amount of energy it will store). How can you get "over 1500mAh" on a 1400 mAh battery? None of you are making any sense what so ever. You can't get more energy out of a battery by charging it a specific way. If I gave you a bucket that held 10lbs of sand and you filled it with 8lbs of sand and waited a few minutes then started filling the rest slowly, it wont hold more sand. This is nothing more than a placebo effect. The only way to get more time from a battery is to reduce the amount of consumption. The only way to do that is to use your phone less or make your hardware use the battery less such as undervolting your CPU. I tried for the longest time to explain to people that underclocking your CPU does absolutely nothing. If you're still running at the same voltage you're still consuming the same amount of power.
Stop messing around with the battery and the battery stats.
Could someone please use the phone until it goes off in the evening? What percentage is shown on the batteryicon when it goes off? 20% or what?

can you give me the idea of how much time should i expect to complete charge of a nexus one battery, while using it. mine takes 2 or at most 3 h. i think ot is fast. should i be worried?
I prefer to charge it while it's off. Using it while it's charging emits more heat than usual, thus being bad for the battery :x.
You don't need to turn it off to charge it, it's true it may become warmer but it's far from being dangerous to the phone and won't harm the battery. How long is your battery lasting? You said you're new to Android so I'm not sure if you've had a smart phone before but it's typical for a smart phone to last between 8-24 hours depending on how much you use it. It will last less than that if you're streaming music and youtube all day.
yesterday my phone lasted 5 h at most. and yes i'm a newbe.
during last night after emptied
my battery i did a full charge while the phone was off. lets see today
The screen is a battery eater, avoid watching movies or playing games or it will last 5h. My N1 battery can last 4 days if I don't turn on the screen but if I turn it ON it loses 1% every 2min
For better battery results:
-Use a task manager/killer app from the Market to kill running apps
-Use Undervolted Kernel (Root needed)
-Use 2G only when you don't need 3G
-Don't use CM Roms because they eat more battery than other Roms
-So far the best Rom for battery is the Desire Rom(but still no BT)
the thing that bothers the most is that 90% of my battery use goes to tbe screen. so it doesn't matter how well i tweek my phone... do you get my point.
i don't watch movies in it. i use a taskmanager as you said, and since yesterday stop using 3G (and i think I'm seeing some diference). it's amazing when you say 4 days (with the screen tirn off) - but to me is a little hard to not using it: I bought this phone so i don't need to allways bring my laptop with me. about what you said about the roms i don't feel able to mess with that.
1. Choice of wallpaper matters. Experiment to see which ones use less battery power for you. (e.g. Magic Smoke live wallpaper is good for saving battery power.)
2. Brightness of screen setting important. NO auto. Select lowest possible manual setting & you still have plenty of light. You can raise level for those instantces when you need extra light.
3. GPS off, except when needed.
4. Seidio 3200 mah battery with provided cover is excellent. No battery longevity problems ever since using this battery. (also using other tips mentioned here)
5. Bluetooth always on, no problem.
6. Wi-Fi on when you need it.
7. 2G/3G switching unnecessary.
8. After total discharge or new battery, let charge at least 12-24 hrs. (this particularly applies to the first few cycles of battery use) After several total discharge/recharge cycles, recharge whenever. Nothing is gained by letting battery totally discharge after that. If you have correctly charged your battery to 100%, remove it, reinsert it, & find % power loss, you may have battery with leak. Replace battery.
I have tried many methods of saving battery, and by far
JUICE DEFENDER
is the best method I have tried yet.
It basically makes it so your APN(Data) only turns on once ever 15 minutes Or when the screen is on.
You can adjust settigns with pay version, but the free version is VERY good still..
Combined with the 850mv undervolted kernels I am draining maybe 3% per hour on average with some light use(regular amount for me, light for most)
I would give it a try. No risk with it.

can you elaborate on that what implicated? and what do i have to? doesn't the phone need to be rooted?
I'm starting to see the light at the end of the tunel. usually by this hour I'm beginning to use my second battery charge of the day. right now I'm at 50% of the charge i made last night (after totally emptied the battery made a full charge with the phone turned of). deactivated GPS, sinc, using only 2G and a lot of self motivation to not touch the screen. it's better, but still made my order at expansys for a backup battery and a dock to use at home with the possibility to charge the spare battery.
today my battery had juice for 13h. from 9am to 10pm. it's a improvement. .. really is.

Dude, my advice - don't worry too much about wallpaper/wifi/BT and all that.
Here's my short battery story.. I bought it 3 weeks ago and no matter what I did, it'd last me 4-6 hours and die. No matter what I did with brightness/WiFi, it made little impact on the battery life.
Now, 3 weeks later, I have:
100% stock AT&T N1
Only 3G, never 2G
100% brightness
more phone calls per day
Wifi/BT/GPS always ON
Always use live wallpaper (gray neural network)
2 email accounts on PUSH (exchange + gmail)
And my battery lasts me 8am to 10pm easy. I just charge it overnight.
So, cycle it (full, complete drain) 1-3 times, then just use it normally. It'll be much better after 2 weeks or so. Also, HTC tech recommended me to use "trickle" charge (charge it with USB, not AC).

hope you're right. mine is now 2 weeks old. i though that was better to charge using AC. i had another cellular some years ago and the battery got messed up because the i charged very often with the computer through usb. are you sure?

I thought I'd write this thread simply to see if it can work for others.
I have read throughout this site that it's good to allow your battery to become completely drained, and then recharge via the power adaptor. Some people even suggest to do it 2-3 times.
Yesterday, for the second time since I bought the phone several weeks ago, I decided to allow the battery to become completely drained. I then charged it using ONLY the power adaptor.
Results?
Before, when in standby mode, no radio, wifi off, screen off, I would lose about 1% battery power per hour through the night while sleeping.
This morning I was shocked. My battery was fully recharged just before midnight, and when I woke up at about 9am this morning, I had lost only 2%. Yes, it said 98% charge left.
WOOHOO!
Anyway, I guess it really does help to allow the battery to drain and fully recharge a few times in the beginning.

I seem to read somewhere that Lithium-ion batteries don't have to be drained to be charged properly. Moreover, it's just okay even if you keep on charging it with the green light on, i.e. reached fully-charged level. Well, I myself just got the HD2 and am pretty satisfied with its battery performance although I haven't really monitored it closely. I just charge it whenever I can.
I recycle my battery about once a month and it really helps.

You are right that it's perfectly acceptable to continually charge the HD2. You can't hurt the battery. I'm just saying that I tried this suggestion (from many other threads) and it seemed to improve my battery situation. It may not work for everyone, but at least it's something.

Peter,
This is the way to treat batteries if you want to get the best performance out of them. There are numerous posts on this issue on here but it does not matter how many times it is mentioned, people still don't read.
What you get is a load of comments about how poor the battery life is without them going through the conditioning process that will get the best out of their battery, irrespective of what type of battery it is.
It is always advised that you go through several cycles of full charge and full discharge, preferably when the battery is new, to get best results, and to do this on a regular basis throughout the life of the battery.
Undertake a good deed for the day; spread the word!

You're right. I've read so many different opinions on this matter, including a lot of research on the Internet. There really does not seem to be any consensus on the matter.
One thing's for sure, I will continue to cycle through full charge and full discharge on a regular basis, perhaps once a month. In the meantime, I'll just top it off every day.
Thanks.

There is a more fundamental point to all this.
Its not the charging and discharging that makes the difference.
Its the working of the battery under load that allows the barry to achieve maximum capacity.
And constantly discharging/draining the battery will have a negative effect over time, shortening life span and usability.
Just charge and use as much as you can.

Strange that all previous phones I had I charged the same way - drain then charge for 12hrs first three times, and then drain / charge as I go - and battery always lasted satisfactorily to me ... I know it is a li-ion battery but for me it works every time and I am sticking to it until they invent better longer lasting batteries

I think he/she means re-cycle as in a charge/discharge cycle
I recently bought a HD2 and was reading very differing advice concerning teaching maximum battery capacity.
-do not let the battery go fully dry, it might harm it (source: wikipedia)
-cycle the battery, drain and fully charge a few times.
-charge as often and much as you can, the battery has no no memory, top it off as you like.
So,,,
I take it now, that the battery likes being used hard, especially when new.
Drain to 7% or so, recharge, drain till 7% or so, a few times.
So do not try to find energy saving mods in the beginning, but work it hard.
I noticed I get a huge battery drain increase when I set the screen backlight to 100 instead of 40. and what a nice display it is
So I figure thats nice way to get to know the HD2, to use it hard and bright, until the battery is 'conditioned' and I know what programs I love the extra brightness in.
I have not been able to drain the battery in a day of expected use yet, always had 23% left or so, which is almost a 4th..
Oh and sorry for off topic, but are any of you guys interested in the ebook reading capabilities on the device at all?
I use a free ebook reader called 'freda' on 'night mode' with black background and red letters, and due to the screen size it is so easy to use the HD2 as an ebook.
I snug into bed and read like 50 pages of an ebook and maybe drift off and the device will auto goto sleep too, if I go first.
It's great.
Have you guys noticed any issue with the charging speed of this phone?
Last night when I went to sleep, 8PM (i know early), the battery was at 9 or 10 percent. I plugged it into the charger and all that. So this morning I go to remove the charger to check e-mail and what have you. 94%.... Come on, its 4:30 AM so that is eight and a half hours and not 100%?
Is this in the experience of anyone else? (Also do not let stock battery meter fool you, it doesn't show accurate measurement of the battery.) If not, what are you guys doing? Or is there anything I can do?
Honestly, 8 hours to charge your phone does not seem right. Something is wrong with your battery. The vibrant does take a long time to fully charge, but never 8+ hours. It usually takes mine a good 3-4 hours when my battery is dead.
I highly recommend download the application juice defender. Research and learn how to use it. It will save you tons of battery.
I'm currently on my 38th hour since the last time I unplugged my phone and I still have 8% battery. Btw, I've been using my phone for phone calls, texting, and playing games.
First of all thanks for the JuiceDefender tip, that looks very promising.
But do you turn your phone off at night to charge? Because I just turned my phone off like 20-25 minutes ago and it popped it all the way to 100% just as I was typing this response.
Any other suggestions, tips, or concerns from anyone, please share.

No, I leave my phone on. Usually with Wifi too.
Also, I have a simple wallpaper that is mainly black (it has some blue designs, but the wallpaper is mostly black). Having a black wallpaper saves battery as well because the color black consumes the least of amount of energy from our screens.
Well my homescreen is pretty black. Black mesh background, black icons (bettercut). Black bar mod. Just got done configuring juicedefender, even bought the pro version. Figure if it doesn't work out I can simply return within 24h. And, I will know within 24 if it is helping the draining.
Leaving Wifi/Bluetooth/etc on will suck your battery down. Turn it on only when you need it. This is true of all smart phones.
My Vibrant will charge to full in a couple of hours from dead. I get 10+ hours on a charge even with heavy use but I almost never use Wifi or BT so YMMV. I definitely get better battery life from the Vibrant than the old G1.
Curious if you could pay attention some time when your awake... my phone rarely charges past 98%. Wondering if your phone is charging up to 94% quickly, and then hovering or if it's actually taking 8 hours to get to that point?
Maybe you should get a replacement.
I can plug my phone in around 10pm and at 6am my battery sometimes says 98-99%, but normally is good to go shortly afterwards. I do turn my phone off at night and those that need me do have my home number too unless I'm traveling.
As well I normal usage is 6am-10pm or so and I have typically 40-60% left on the battery depending on the usage. Yes I do check the About Phone and not relying on the wacked out battery meter.
I don't leave wifi, gps or 3g on all the time simply because I don't need them. Id rather squeeze the battery than have something on that isn't being used anyways. Having that quick settings drop down in the Notification bar rocks.
I have the same issue. It always takes about 4.5 -6 hours to 'fully' charge my Vibrant from <10% regardless of whether the phone is on or off. Then after unplugging the charger, the battery info states that the battery is charged to 96%. My belief is that there are firmware issues with at least some TMO Vibrant phones. I'm also dubious of the USB charger. I've ordered a regular charger and I'll see if my suspicion surrounding the USB charging system is founded. Maybe...

Mine takes about 3 hours to charge but I normally get about 13 hours a day on it with normal to serious use. I haven't had a problem with battery life since I purchased it but I have been trying new battery saving techniques to see how long I could make it last.
Currently using a mostly black background. Wifi only when I'm in the house. Brightness all the way up. Synching two email accounts and Facebook all day. Definitely getting the most out of the battery that I could expect.

Well mine takes a while but not that long. I'm going to try out the juiceDefender that was mentioned but the other thing I would recommend is the accurate battery mods that can be found in the Themes and apps section. You can flash with clock work and it's a great way to know what your battery is actually at so you can see how much you're using for various things.
Make sure your charger or USB port has high current output. There are some out there with only a few hundred milliamps. The phone will take nearly one amp and should charge in a few hours.
Excellent point. For me, I'm using the supplied Samsung USB to 110v adapter and I'm getting 4.5-6 hour charge times.

Also the USB cable is important too. 1 amp over a long, skinny 5 volt cable can drop the voltage. If the charging chip sees a lower voltage, it will think the USB port is at capacity.
I love this phone but I must be honest.. this phone is worst as the Motorola cliq battery wise. it's terrible. I had 100 percent battery life at 8am and at 10:50am I had 23 percent battery left............ no matter what I was doing.. even if I had the screen on full blast *i had it on the lowest* it still shouldn't be almost dead in 3 hours .... smh!

One poorly written application running in the background could be causing the CPU to wake up constantly. Yet I can talk for hours and the battery will still be nearly full.
I know for sure one of the latest versions of Facebook ate batteries like crazy. I ended up installing an older version and my battery life returned.
Update on the issue. I was using juice defender but it wasn't doing anything for me as far as I could tell. I have since turned off vibrate on touch, and noises coming on during clicking. I am using a usb hub with two vibrants on it. I'll plug it into the wall tonight and see how that goes.
I have been turning off my wifi when not using it. A little better I suppose. While typing this I went from 49 to 46 percent and I am a fast typer. No wifi bluetooth gps.

Yes the battery drains pretty fast, and it does take about 3 hours to charge... my main problem is... at night when I plug in to charge, couple hours later I get woken up by a beep and popup window telling me charging is done and to unplug...
anyone know how to turn that off?
So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,

Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S
I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.
But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky
I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.
The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.
Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?
Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

Those damn birds aren't content to kill pigs; they have to go after our batteries too!

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.
I wouldn't exactly call this an issue because it doesn't really affect how I use my phone - it's merely something odd that has me curious if anyone else has it:
If I charge my phone all night, and plug it out at 100%, then no matter what I do it'll stick to 100% for a long, LONG while before it hits 99% - we're talking..25 mins of sat nav, and spotify, and full screen brightness on the go. But then, it falls down into a more regular pace of discharging.
If however I unplug it 5-10 mins after it hits 100%, it starts discharging normally.
I think I can get a batter life of full browsing of 6 hours, probably. Maybe a bit more (never tried it, never needed to).
I am just curious why this happens with my LG. Do you think it's a fault or is it fairly common?
Thanks
P.S. - testing it again now - 15 mins in youtube watching a video, still at 100%. very strange
you seem to have found some interesting sweetspots of charging and battery depletions.
My instinct tells me the discharging and the 100% mark is influenced by code in some way other then the battery being truly at 100%. There is software like android tuner or battery widget that monitors stuff.
however a great dev already wrote something about tinkering on lg's side in reporting the battery. Which means the percentage is. indicative but completely reliable. To gain more indepth into the actual battery usage other apps are needed. If have battery ocd that is.
I would report this to lg, just to be sure nothing else is happening

what is more interesting is that this happens to me both on official LG, and on ROM (cloudyfix).
Continuing with my tests, I have been running youtube on repeat since unplugging and monitoring. I am now at 50%, with...close to 5 hours of usage?
then its playing from buffer and not continiously downloading and streaming right?

It downloaded all times. I plugged the phone in to charge at 10÷.at that time I had 7:30 hours YouTube screen time on auto at 90÷ . I suppose this is a good performance?
its great performance

yeah i thought so.
So I'll leave with that little flaw I think, I'll just learn not to mind it and be sure to always charge overnight to get the best next day. Thanks for the help
I usually charge my phone and reboot it right after it hits 100%. I don't disconnect the charger until the phone restarts completely.
Doing that I get outstanding battery life
