Hi everyone!
I'm getting my prime and dock delivered today, and I can't wait!
(32gb gray, tiger direct, pre-ordered 11/25)
I have a question on the charging it 8 hours rule before using it for the first time.
I'm okay doing it, if that's what manufacturers say will prolong battery life.
(Anyone didnt do this?)
So I've read the only way to charge the dock is to attach the two together and charge it as one unit.
If that's the case, do I charge both for 8 hours, or does it have to be longer because its combined?
Thanks in advanced!

I think you should fully charge your battery.
When I got mine I didnt charge it fully and had terrible battery life, after maybe 10 charge-discharge cycles I'm having much better battery life.
Concerning the 8 hour initial charge: I didn't do it. I charged it until it was at 100%, applied the updates and after they were successful i unplugged my prime. If it says its full it is full. Thats how i see it. I'm not a battery tech or anything but to me it seems strange that it would make the battery way worse if i didn't charge it for 8 hours. As far as i can tell right now (had my third charge last night) the battery is fine and i get the expected runtime. Mine made it two days without recharging (with about 3-4 hours of hd video playback each day).
Btw: In my (german) manual it says that i should always charge the prime 8 hours or more but why should i if it is full after 3-4 hours? If this makes my battery die in 3 instead of 3.5 years screw it.
I always, always break in my batteries for any devices and I've always done it the same way. I have never ever had a single bad experience with shortened battery life span or the battery not being able to hold it's max capacity charge.
Here's what I do:
1) Upon unboxing, I completely drain the battery by using the tablet. This is the best time for you to set it up, re-download the apps (restore from Titanium Backup if you've got root), play with it a little bit, etc.
2) Charge it overnight or around 8-10 hours. Even if it says full, leave it plugged.
3) Completely drain the battery again just like in step 1.
4) Repeat steps 2 and 3 again (2nd cycle).
5) Repeat steps 2 and 3 once more (3rd cycle --the last one).
You're done! Now you can charge your Prime whether it's still 90% or 5%. At this point, try not to forget your Prime plugged in after it says full. Once it says full, unplug it. You can always clear battery stats using recovery (once/if you've rooted) or use those battery apps that can calibrate your battery. Also a note to those who will use custom roms and/or kernels, you might have to do 2 cycles of full charge-discharge, preferably after wiping battery stats, so that your battery can readjust to your new rom/kernel combination.

Your battery can only reach it's full capacity (read: x hours of use for y number of years) if you break it in properly and treat it right. It's not true for all types of batteries but I think it applies to Lithium Ions (Li-Ions), Lithium Polymers (Li-Po) as well as NiCads(?) and maybe other older batteries. You can read about it everywhere if you Google.

My English manual only says to do the 8 hour charge when new and any time after the battery has been fully discharged... which isn't the same as always.

That's interesting. Mine just says when the battery is "leer" (empty) it has to be recharged 8 hours. Looks like the true meaning has been lost in translation.

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... ?

Yeh, that wasn't actually my point, but thanks anyway!
112 now...
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.
Newbie here - I have a stock G Tablet.
Have added many apps and also Flash and it is working great.
My one concern is that however long I charge the unit,
I can't get the battery indicater to go above 93%.
Is anyone else experiencing this ?
hello there,
yes i am having the same problem. no matter how long, mine can't get past the 95% mark. clockwork mod + tnt 2.2
ideas on how to fix this, anyone?
regards
Try to recharge with the device powered off, and let it charge for at least half an hour after the light turns green.
I've left it plugged in a good 2 to 3 hours after the green light came on.
It still only reaches 93%.
Is it a bad battery, bad charger, etc.,
Any thoughts... anyone ?

Do a full cycle, all the way dead and then charge as stated for about 30 minutes after the green light comes on. It could be just a calibration problem. How long is the battery lasting for you?
I use it for short periods throughout a day, so it is difficult to gauge an accurate time.
A rough guess would be approximately 6+ hours.
I always thought it wasn't good to totally drain this type of battery ?

I think this is a LiPo battery - if so, then its is OK to let it drain all the way - just don't do it too often. You should *always* do two full discharge/recharge cycles on any Lithium-based battery as soon as you purchase it, and again about every month or two.
For removable Lithium-based batteries (i.e. *not* for gtab!), if you aren't going to use the battery for, say, more than a week, the best thing to do is to discharge it to about 50% and then put it in the refrigerator. When you are going to start using it again, let it warm to room temperature for at least a few hours to a day (depending on how big it is), *then* put it on the charger. Absolutely do not charge the battery cold as the thermal shock could damage the battery.
The initial discharge/recharge cycles "primes the pump" so that you get the maximum capacity out of the battery (who knows how long the battery has been 'sitting on the shelf'), and the ongoing discharge/recharge cycles keeps the battery at its maximum capacity *and* allows the calibration electronics more accurately track the slow decline of the battery's capacity.
BTW, my gtab's battery lasted on-and-off for almost 2 1/2 days. That was 'sleeping' it at night (*not* turning it off!) and using it on-and-off wifi/surfing/playing AB during the day. I must say, the gtab's battery life is phenomenal!

Thanks. Tried the full discharge and then full charge with the gtab turned off, left for about an hour after the green indicator, but still stuck at 95%. Even deleted the batterystats.bin file. no change. must i do two cycles of full discharge and charge?
I'm having similar issues. I powered off my gtab overnight and let it charge for 8-9 hours and I have not been able to get the battery to say 100%. I'm going to leave it on all day and let it discharge completely and try again tonight.
Drained battery and left it charging overnight and while I was at work (15+ hours) and its still at 95%. I wonder if I should exchange it now.... I'll give it another week....
If you do two full discharge/recharge cycles and the battery is still not showing 100%, then I would take it back. Either it is the battery or the battery calibration electronics that isn't working (my bet would be the battery). Furthermore, since the battery is "not removable", its just not worth keeping it and taking the chance.
If the battery had been removable, then Viewsonic could have just sent you a new battery instead of having a whole gtab come back....
(Note for Viewsonic - this is where removable batteries are superior to non-removable!)

Before you return it check the actual battery life. If it turns out that it's just a calibration issue and if your happy with everything else, perhaps you should keep it.
Read the thread about my battery test...
mine is different... I can charge up to 100%, and keep using it for few hours at night, put it to sleep, then I wake up in the morning and find the battery completely drained... any1 has the similar issues??

You can try going to settings/applications/running services and turn off all non-essential services before putting it to sleep.
Mine doesn't get above 96%, will have to try the suggestions here but overall I'm still very happy with battery life of the 96%...
thanks, i'll definitely try that... but I don't think I have too much installed or services running since I flashed it with the new ROM.
have you guys notice your battery temperature? i got 2 gtab but both operating at different temperature 1 at 23-24 other is around 31?
My battery life seems pretty good even though it doesn't go higher than 95-96%. I saw in another thread to try resetting battery statistics in clockwork recovery to see if that will fix the battery display problems. I'm going to try that next.
I've got the Malata Zpad (SMB-1002-3G) and mine now wont go over 91% (happened on the 3rd day). It used to charge to 100% no problem for the first two days.
I did a recovery (format) when you press the power and volume up button, but that didn't seem to do anything (other than wipe all my settings and put it back to original factory settings of course)
I'm pretty sure the battery is fine, and lasts just as long, but it would be good to be able to reset the battery status.
PS: My Zpad is not rooted or anything. It's pretty much standard (just running Launcher Pro).

Do you have Clockwork installed by chance? If you do you can charge the battery all the way up and then go into clockwork and reset the battery stats.

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 am havin HTC AMAZE 4G
when i used to charge it before
phone used to come to 90% from a full in approximately 1 hour.
now it comes very quickly like 10-15 minutes
& also the major problem is my phone gets switched off at any battery percentage like 65% & when it gets restarted it comes to around 8% or sometimes even 4%.
if i pull out battery again restart the phone then sometimes it comes to around 30% back or any random increase in battery or sometimes even decreases to 4% & then the battery gets drained in 5 minutes & i have charge it again
battery takes more time to even charge
sometimes using DATA & charging it even takes 10 hours to charge
i dont know what is the problem
i have been thinking about battery problems
but i googled & in some blogs it shows as circuit problems too
the problem is i am living in INDIA
this phone is not official here so the service center guy wont touch it & i dont want to waste money on the battery if it isnt the problem
USING HTC ICS OFFICIAL ROM
NOW BATTERY LASTS with normal data on maximum 4 hours
help me out guys
thank u
How old is your handset? Battery life decline is normal as it ages. Without being able to inspect and test yours out all I can tell you is the most likely explanation for what you're describing is battery wear.
The original HTC battery that came with my phone only holds 2/3 of the charge it once had when new, which is why I invested in a pair of Anker batteries and an external charging station (I purchased them together in a package on eBay for under $30 US shipped). Having the extra batteries has been an excellent addition. I alternate them every few days to more evenly balance how they are wearing and to prolong the remaining life of my original battery. Plus it's great to have an extra battery to use for those times when I really need my device, but don't have the ability to plug in.
Check out the best battery thread in the Amaze accessory section for more details and comparisons.
I hav been using this phone for 1.5 years
tried using battery of my dad he uses same phone.
It showed 56% in my fathers phone
Wen i switched the battery &; started my phone it showed 15% at start
So what could be the problem then?

You're getting the different results because the batteries aren't calibrated to each phone. If you put your fully charged battery in your father's phone it shows 56%, correct? What happens when you put your father's fully charged battery in your phone? Keep in mind that when switching around the batteries neither with be calibrated to the device, but will instead show a percentage vs the battery that was properly calibrated.
Example: the battery in my phone shows as fully charged, but is worn and no longer charges to the maximum. If I place it in my brother's Evo 3D which uses the same size battery but is newer. It will show as only partially charged because his device is calibrated to his newer stronger battery. Conversely, if I put his newer battery in my phone which has been calibrated to my older worn battery it will appear to be fully or nearly fully charged for a long time before it begins to show it's draining with use.
The only way to properly test your battery would be to either try a known stronger one in yours for several charge - discharge cycles as your phone calibrates to it, or to try your battery in another device for several such cycles. Then you need to compare if there was an improvement in up-time or not. Short of taking it in to be checked on diagnostic equipment it's the best method I can think of.
Good luck!
Thank you very much for the reply
Goin to a local mobile repair guy for a hardware check
Will tell you the results tommorow
Thanks once again
Maybe you just need to wipe battery stats. One trick that works is let it drain completly and let it be drain over night and charge it again keep doing a couple of days it may just get better. But think is just battery problem not hardware related.
My Original HTC battery worked its way down to 2 hours of usable talk time. Eventually, got so bad that it barely charged on anything but a high current wall charger. Technically it was under warranty at the time...
Ordered 2 Anker Batteries w/ charger for $30, and not long after that the charger broke. It quit charging batteries.
I then just stuck with one Anker battery in my phone and the other as backup. The battery I used the most is now down to about 4 hours of life on a full charge. The least used is about 8. I try to keep the worse one charged up as a backup in a pinch and now use the good battery full time.
Just how life goes sometimes...

Yeah that Anker charger is the weak-spot in that 2 battery package deal. The damn thing is flimsy and fragile. I'm so paranoid about breaking it I treat it with kid gloves. The batteries are pretty good though. The package was one of the best investments I made since owning the Amaze. Using indelible marker I labeled them 1 and 2, and rotate their usage with my original HTC (which is easy to distinguish). This way when I'm on the road I always have one fully charged spare handy, one charging at home, and one in my handset.

Agreed!
But When I was using official ICS from T-mobile, I had the same problem, even after wiping. I even faced a funny thing. Percentage of battery in bar was different from percentage shown in lock screen!!!
After flashing custom rom, All problems GONE!
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%.

Not all devices may say it, but all should be charged before initial use.

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.
