Hey guys, both my and my gf bougth and Arc, when i bought mine the dealer recommended me to charge the phone for 16 hours before i started using it. I think i was in a hurry the next day and the phone only got 9-10 hours.
My battery time is not great but not bad either, first 15% goes fast, then it kinda slows down.
My question is is it a one time chance you have to charge the battery first time you get it, and if you dont do it proberly well too bad? Just curious how long you guys charged it the first time and if you think it matters much??

16 hours seems a lot, I've only ever done a few hours (3/4) which has usually given a full charge, but I do cycle my battery i.e will let it drain fully (below 10%) before recharging.
That whole "16 hours" thing is BS.... that sort of treatment is not required for modern batteries.. and in any case the phone will stop charging when it hits 100%.. the only thing that seems to help is to run the phone down to about 20% a few times (through normal use..) but I've also read that a complete discharge every now and again helps..
it helps to cycle
16 hours is as said before bullpoop.... 100% charged and it will stop
the battery tech is li-po. lipo bats are ment to be 100% discharged and then 100% recharged....(trickle charged if possible) not sure how a phone charges there bats though
lipo unlike other types actully do have a proper memery and if you keep half charging or dont let it run right down the bat will over time last less and less......
even then they dont last forever i replace mine every year with a new set (i say set as i own 2 bats and carry the spare one with me when im out hard usage i can get half a day out of my phone so 2 bats works for me. i no longer use my phone for charging i have a battery dock that now charges my phone
hope this helped

I am wondering whether the charging methods make a difference to battery life?
How do you charge your battery, and also your initial charge from new?
This is the first phone I've had that I didn't leave the initial charge on all night 16 hours initial as recommended by most phone manufacturers, and I just took it off after a few hours when it was charged up. Do you think that affects the performance of the battery? I've never charged it for more than a few hours. The main reason I don't leave it on all night is because it gets really hot, so when it goes green light, it's done for me
Do any of you let it run out past the amber warning colour as a completely flat battery is probably better to charge?
All my other phones were left on charge all night, every night, but they weren't this type of phone.... and in truth, it makes no difference whatsoever to the battery. The Motos also needed charging every day
Stunning work guys, 56 views by people I can only assume own the Hero, and nobody wants to divulge their dirty secrets about battery charging... Thanks anyway
Just look around google for Li-ion recharging, there is plenty of resources to read up on when trying to keep battery life at a maximum.

probably because the hero is so new that nobody can tell anything about the battery life? and i don't suppose any of the 56 people has two heros and did the experiment of charging one full and the other for 16 hours, only to use them in the same manner afterwards and count battery life... ?

I was wondering how many people just got the phone, and charged it 16 hours initially or couple of hours and go, and do they leave on all night despite it getting hot.
Not hard...
You should charge it until it is fully charged but not leave it on charge extensively - excess heat may cause the battery life to reduce (although I wouldn't know how much degradation this would cause). It is probably ok every once in a while to leave it on charge overnight, in theory the phone should have circuits to protect against overcharging it anyway. 2 hours is about right for a charge cycle. You should charge it when the phone advises to do so - 15% or less charge. The Lithium Ion battery will only recharge cycle effectively a minimum of 300 times but I would estimate conservatively that is the number of times you can recharge. 2 days between recharges would give you about 2 years life out of a battery. I recharge it every two days, and charge time is about 2 hours.
Yeh, I have to charge it every day though......... Never lasts longer. I just wondered if you were supposed to do the initial first charge overnight and whether it sets the standard for the length of time you get each day after that?
i guess every hero is different. longest i used my phone without charging is 2 days with moderate use.
before i charge my phone i kill all tasks in the background and clear my browser history. might not make a difference but to me it feels better to have a fresh phone after charge.
Is that with the task killer app, or is there another way?
I can't imagine mine ever lasting 2 days.....

I'm using TaskPanel as a taskiller...
when i got the hero the battery was ~half full. i charged it for about half an hour, but had to stop the charging before it was full.
the battery doesn't last longer than one day, although i play a lot with it (obviously). when i put it to the charger i try to let it charge fully up, and i noticed that the charging is stopped when the battery is full (you see the icon in the not.bar go back to normal green battery, and the phone cools down noticably after charging is completed). concerning this i have no problem to leave it plugged in overnight. checked last night, when NOT plugged in it takes 4% of battery for ~7 hours in airplane mode.
So the original battery in my phone.. well... sucked. When I pulled the phone off the charger it would jump down to 93% no matter how long it was on the charger etc. Any attempt to bump charge was thwarted in the fact that I cant charge the phone when its off (it automatically turns on and boots into CWM). Wiping the battery stats when the battery read 100% in the OS would still result in the above.
So I ordered that 1600mah battery from Seidio. Ran the charge out of it yesterday and charged it to full during the evening/night. Wake up this morning, pull the charger out of the phone, and BOOM 100% power. Not 93%...
So was it my old battery that was bad or was there something wrong with how the phone saw its power rating?
From what I've seen with the phone, it drops down to 90% or so before it starts charging again, but it won't ever have the display show a battery decrease while plugged in.

Right but I can watch the meter go all the way to 100%... pull the plug and it goes down to 93% within seconds.
funny thing phone did the same thing...took it off the charger this morn and it dropped down to 95
I'm at 99% after about 2.5hrs of mostly idle usage. I've been just rebooting the phone with it on the charger in the morning, give it about 15-20 minutes and usually it'll stick at 100

All you are doing is semi-bumb charging it, which is fine if you really must have that extra 1hour of battery, but be warned, doing it constantly will damage your battery over time. that is the reason the phone has built in charging/decharge in the first place.
The reality is if your phone is sitting idle, that 5% wont matter at all once your phone attunes to your battery, and if your using the phone so heavily that your going dead long before the day is done (after attunement) then the 5% still wont matter !
i was having the same issues - 90% right after unplugging. had to charge the phone 3 times in ONE day and i never even touched the phone the whole day except to check the battery percentage.
brought it into verizon, they gave me a new battery and now it lasts me the entire day. when i pull the plug out now, it drops steadily like a normal battery should. i tried bump charging before i brought it in and it didn't help at all
The same thing has been happening to my dads Thunderbolt.
He charged it overnight, took it to work and was losing about 1% per minute without touching the phone. The only time it was touched was about 1 timer per hour to take down the battery percentage for his log.
He took it to the verizon store and they told him he should not expect anything longer than 4 hours of battery life without touching the phone..what kind of BS is that?

I'm having the exact opposite problem with the batteries--just ordered two of the 1600 Seidios that delivered yesterday and even after running pretty much down, fully charging overnite with the T-bolt powered down, drops to 95% immediately. Conversely, the OEM battery would stay at 100% for hours if the phone was idle (screen off / receiving any emails and SMS). Go figger.
There is a post in the Android Central forums on the 1600 battery compared to stock. After testing, they found that the two perform almost identically. Basically, it isn't worth replacing unless you go with the big HTC extended battery. Although having a spare isn't a bad idea. If only that battery door wasn't so tough to pry off when you need to change it...
nexus s had the same problem its nothing big though

Most of us probably won't have the phones long enough to see any possible damage. Starting off at a full 100% is a lot better than immediately dropping to 95 or so after pulling it off charger. It's kind of like the gas gauge in my truck. Stays full a while but once it moves off of full you can watch it drop. lol
Good day people, I have a dumb question and no need to be polite I know its dumb lol I just got an evo lte and I love it so far. But I did some reading up on training batteries and I'm aware that you can't necessarily train a lithium ion battery but I know there things that you can do help the battery last longer etc.
The first day I did my normal routine, drain it all the way charge it all the way. It took a long time for the battery to die which seemed like it was a good thing. I did that twice and I noticed that after a full charge the battery drops to 97% fairly quickly (like withinless than a min or 2) and from the few days I've had it it seems like it may not hold the charge well over time . I wouldn't normally be concerned about this however this is the first phone I've owned without a removable battery, I don't want to regret it 6 months from now because the phone only lasts 5 hours.
So my question is this I am still within the buyers remorse period should I just exchange it for another onevor am I just being too paranoid? Secondly how do you all train your batteries when you first get the phone? What works for you all who own this phone?
Thanks in advance.

First off, congrats on your choice. This phone has a Li-Ion Polymer battery, which is different from the Li-Ion batteries of yore. I am stock rooted and with medium to heavy use I get a day<12+ hours> out of a full charge with no batt training. I have not experienced the rapid discharge you speak of and if you have no apps causing it, you may need to swap it.
I also get a pretty rapid discharge from 100%->98% - takes about 5 minutes to drop that 2 percent. But after that, I am clear sailing for ~15 hours.
Oh so the rapid discharge thing isn't uncommon then? Hmm

I don't know if it's the same as the og evo and the 3d but when it hit 100% try unplugging it then plug it back in for a few. That may give you the true full charge and stop the quick 2% drop

Yea I'm kind of torn on exchanging it. I may just do it. Of course it would be my luck to get a phone with issues if I did.
That's normal. If this is like the OG Evo (and it probably is), the phone will charge to 100%, then let the battery discharge to 95% before charging back to 100% again. This is primarily to protect the battery and prolong its life. So while the phone may claim to be at 100%, it could be as low as 95% when you unplug from the charger. The rapid discharge you're experiencing is really just the phone adjusting to the actual battery level.
Also, there's no need to "train" the battery. I seem to recall that it's generally not healthy to discharge a Li-Po battery to 0%, and can shorten the life of the battery.
The battery percentage drop you guys are seeing is perfectly normal. No need to exchange your phone. As soon as the kernel source is released by HTC, then the great devs here will be able to bless our phones with some SBC goodness and you will not have that problem anymore
You guys don't think I did any noticeable damage by fully discharching it twice do you? I'm going to charge it and see what happens I don't have any immediate thoughts of exchanging it based off of what you guys are saying. I'm going to charge it up and post results. If its not like what you guys are getting life wise I may exchange it as I still have like 5 days left.
Minor update 7 hours 27 minutes 52% left.

No, it's fine.
Fully discharging it just reduces the number of cycles left you have. Most li-ion batteries have 1000 charge cycles. Battery charge is not an exact science. Do not look at it like you are not getting the full charge.
So at the end of the day it looks like roughly 8 to 9 hours of moderate to heavy use on my phone moderate for the first 7 hours heavy for the last 2 and some change. Does that sound about right?

I have this doubt since purchasing the Xperia Z!
As soon buy my Xperia Z2 and the store where I will buy it is difficult to leave the charging device 30 minutes before turning it on to test it!
As difficult as it was I let mine charge for an hour or so before I used it. Not sure if I needed to but was in work at the time so had a few things to keep me busy while charging

My phone had 62% battery when I recieved it. Probably my contractor that installed some apps and charged it. I didn't charge it untill it was empty.
I wonder what is the need to leave charging for 30 minutes before turning on the device for the first time since the other brands of devices do not need it!

Mine also came with 60% battery when I got it, I think its normal to keep a charge in the battery because it helps battery life.
I let mine drain right down that first day then I charged to 100% overnight.
I currently get to end of day with around 50-60% left
You should always charge them to full before first use. The charge that's in there is only a manufacturing charge, which is enough to keep the cells active.
Also, you shouldn't drain it completely. Lithium works best from around 30%-80% charge.

What I find strange is why other brands of devices do not have this rule??
Li-ion batteries don't need to be fully charged before first use. They don't suffer from "memory" like Ni-Cd. But it is true that for best life you should charge it between 20/30%- 80%. If you plan on storing the phone without use for a long time, best is to charge it to 50-60% (not 100%) and put it away.
Go use and enjoy your phones!
PS: A few laptop manufacturers (like Samsung) have an "extended battery life" mode that you can enable where the battery stops charging at 80%.

You're right, they don't have the memory effect, but they do need charging before use. But yea, storing with at least 2/3rd charge is best.
BTW I sell batteries for a living, have done for 15 years.
Ok so is the correct answer yes, charge for 30mins or not necessary? Seems both sides of argument has support

As an electrical engineer I have to say: You should charge it before first use. 30 mins charge should be fine.
Well, it might be not so obvious for the battery in Z2, as it was manufactured not a long time ago, but it could end up in battery degradation, if the battery has been stored for a long period of time without usage.
Ok so with the Z2's being manufactured within the last month it probably isn't needed then

Well, it's hard to say. Precharging the phone won't hurt.
I charged my first z2 for half an hour, and my second one was up and getting flashed within ten mins. I actually found the second one to be better on battery. I do agree that if the phone has been sat dormant for a long while you should charge, but as these things have literally just been made it'll make zero difference.

My old phone's (Xperia S) battery drains very fast (can't last for a day) after 2 years of use. When it was new it lasted about one and a half day. I charged it every day for 2 years and the battery became weaker. I don't want this to happen with my Z2. I use dock for charging my Z2. USB cable or dock is better for the battery? And when should I charge it? wait while the battery drains full or charge it every day and don't let it drain, just about half, or don't charge it full and get it drained every day. And how long should I charge it? just that time while it charge full or leave it charging for longer (a whole night, about 10h)
someone please
I dont think it has anything to do with the way you are using to charge your phone... It's just natural for the battery to need to be replaced after a couple of years as far as i know
As far as I'm aware, after about 500 charge cycles the battery stops charging to full capacity (although it says it is). So the battery quality degrades over time regardless.
the battery of the Z2 is hardly affected by how you charge or how many times its charged
itll start degrading over time
it should be a Li-ion battery (referencing the packaging instructions for Z2)

just charge normaly,
somehow i get the best life out of charging randomly, e.g. never 0>100% or simular but instead 20 to 60% increments gives me the best total life
in terms of wear, cant do anything with a Li-ion battery as far as i know
ok, better charge it when it gets as low as 30% and better not fully charge it, but 85-90% will be great for long term life. and never let it connected if it happened to reach 100%, also better keep it somewhere cold and definitely not under sunlight
It is said to live longer if you charge it from 50 to 90%.
That said, if you charge it from 0 to 100% every 2 days, or charge it from 50 to 90% ever day.... well... the end result is the same... it doesn't matter at all.
The battery already has safety over/undervoltage protection, therfore charching it as you like doesn't change much at all. You will see that a phone left at 100% in the charger will drop to 97-95% before it starts charging again.
i think the battery in the Z2 was said to handle about 600 cycles with less than 10% Battery degration.
if you charge it every 2 days thats about 3.5 years.
There is a lot of false information floating in this thread.(and lol Z2 deals with all, 10/10 loyalty) I was actually replying to this but I wanted a bigger audience to take better care of their battery, so check my thread out : http://forum.xda-developers.com/showpost.php?p=60299964&postcount=1
