hi all, my nexus 7 is gonna hit 3 years soon and i believe the battery is getting old. i get about only 3-3.5 hours screen on time nowadays. i remember i used to get 6hrs+ at first. this is normal right? the battery is supposed to last how long? i rarely let the battery reach 0%. i recharge from 20-30% to 100% for most of the time. my usb port is completely damaged as well...i charge from pogo pins. where can i get a new battery/?

Hi,
I am getting a MDA and i want to get the ultimate battery life out of it. So it should be arriving soon, and i want to know how to start getting the most out of it. I have looked on the board at the horror stories of batteries lasting not so long. I have experienced that as well.
This is a replacement unit for a USED MDA that i bought. So i have no idea how the previous owner charged it. But i get only about a 24hrs out of it with hardly any use on it besides a few calls.
I will not open the unit till i get a few replies on the initial charge and charging thereof.
Please post your battery life and how you charged and continue to charge the battery and phone now.
I plug my phone into the wall.
It's a good idea to charge the battery completely before using the device, then do not charge it again until it dies. Run at least several cycles like this - this helps the battery last longer in the future.

Ya, after searching through the threads i get mixed opinions. Some say do that. Others say keep it tipped off. I am in half a mind.
pda battery is a bit different from phone battery.
while new phone battery need to charge at least 10hrs in order to achieve max performance, is it different with pda battery.
you dont have to charge that long before you use it. just make sure it is fully charge and when you are not using ur wizard, just plug in to ur usb cable. the more you charge it the longer it will last.
I wouldnt worry too much, replacement batteries can be obtained from Ebay for about 14 quid.
I basically have mine connected to my PC all day so it never really gets very low apart from at the weekend when I'm not at work but the charge will usually last the weekend unless I do a lot of wireless surfing.
i fully charge mine every few days. i seem to get a decent battery life off of it with moderate use (about 60 mins worth of phone calls a day, texting, mp3 player for 20 mins a day, gprs/wifi for about 10 mins a day) i have quite a few programs on it that would drain the battery moreso, but at the end of the day ive usually got about 60% battery left. my phone is only 3 months old mind.
if i forget to charge it, and whilst in the office, a simple case of plugging it into the pc keeps it topped up
hello
just recieved my HD2 and I've drained my battery to 0%. now I was wondering how long will it take to 100% charge again.. 3 hours? 8 hours?
deiota
ps. Ive done my first 12hours charge already
With the original charger, about 2hrs if you don't use it at the same time.
yes Im using the orginal charger and the hd2 IS power off.
the stuff about charging for hours when you get it and then draining it right down no longer really applies too our batteries.that was for nickle batteries to initialise them and prevent the memory thing. with lithium ion they no longer suffer from battery memory.
ýeah it took about 2 h
2 and half ours starting from zero charge
I never did anything with the battery when i got mine!! Was way to eager to play! Never had any Battery issues.....
I did loosely time it once as i wanted to know what difference a quick charge would make and it seemed like it went up a percent approx every 3 mins... trouble is that doesn't quite equate... it would mean that from 0 - 100% would take 300mins (5hours)! but in reality it probably takes between 2-3hours..
I guess either the battery doesn't charge linearly or the percent display is inaccurate...
I Did a full charge at lunch time since it took me 1day and half till battery to drain completely,
I wonder if I should put it on charger all night long (its 10pm now and I have 80%) or should I let it out of charger...
If your battery needs charge, then charge it. There is NO NEED to completely discharge it and then charge it for sveral hours. In fact, modern li-ion batteries will take damage if _completely_ discharged!
The thing about completely discharging and charging for days is long gone! Batterys have evolved, we dont live in the 1990's anymore
HI, I'm going to receive my phone this afternoon..just confirmed by DHL Malaysia.
can I know how many hours you guys charged your SGS2 for first time battery charge.
Is it necessary to charge 8 hours for first time use?
Please share your experiences
for my past phone , nexus 1 and nexus s, I charged 8 hours for first time use and 8 hours for my extended batteries as well..
from my understanding, you don't need a extra long first charge for Li-ion batteries, you only need to prevent overcharge/overdischarge which is taken care of by the battery protection circuits.
In other words, turn on and start using it like normal
Just plug it in, charge it. When it's full unplug it.
Took me 1h to charge it up from half. Battery came with half charge.
Thanks mates, I'm charging the phone now
until it's full, I will unplug..
Try to run it through a few full cycles when you first get it though...
do u mean it has to be drain out before next charging?
I think it's a good idea to go from 0 to 100 in the beginning. Not for the battery sake more for the phone to learn what max and min are.
Hello Experts,
I received a new nexus 4 and noticed that it takes around 3.5 to 4 hrs for complete charging from 5% to 100%.... is it normal? my other sony xperia seems to be charge in about 1..5 hr
since i am new to Nexus 4, not sure what is the avg charge time and should i call for RMA? Please let me know what is the avg time for charging.
thx

Perfectly normal. You want a nice slow steady charge, especially in a sealed phone. The battery needs to last as long as possible. Fast charging batteries significantly reduces their lifespan. My old Nexus S takes the same amount of time to charge from 5%.. 3-4hrs or so give or take.. I still have the two year old original battery and it holds a charge just as well as it did the day I bought it. Meanwhile my 15 minute charge AA batteries I bought last year lose their charge in a week just sitting on the desk.
Mine is just about the same, but that's under use. If I don't touch the phone, it typically charges to 100% in about an hour.
And if it's through USB.. um.. more like 8 hours to fully charge.
Battery widget reborn (awesome app btw) says my phone usually charges in about 2.5 hours. This is on Qi though not sure about the regular wall charger.
2-2.5 hours for me on usb wall charger and Qi Orb.

I concur.

From 2 hr 45 min (from around 12-15% juice left), my charge time has reached to 3 hr 30 mins now (i.e. from 1% juice left)... 14% juice wouldn't make such a huge difference so don't really know why it increased..

yes, this is one of the reasons i started this thread to understand what everyone is experiencing.... i called up the google customer support and they are ready to send in a RMA as it appears to be a higher side...
so let me know your thoughts guys...should 3.5 hrs charge time considered high and warrant a RMA? share your thoughts.
^ Hmmm.. I doubt if this would mean anything serious or worth RMA-ing. I can but I won't RMA my device because it's been exceptional so far. I am fairly happy with it and wouldn't want to get it replaced with a defected one.
Its perfectly normal especially from around 5% to 100%.. In my experience if you dont let it get below 20% it usually charges faster. I wouldnt RMA it especially if your phone is perfectly fine in other aspects.
I tried with a different charger yesterday and it took similar time. The charger has same voltage input levels.
You charge 3 hours, for only double the lifetime. How pathetic, actually. I didn't thought that the battery life would be that bad. I can hardly make trough 1 day, if I play some games, make some calls, and use a little bit of internet. On the last charge I got 4Hours of screen on time with 15% left.
Gosh, at least it's fun to use it. :/
So, I'm getting the new Nexus 7 in Australia when it's released here soon (Early September) and I was wondering, how should I manage my charge cycles?
With my current phone (I have no tablet), I charge nightly, sometimes the battery may be half full when I start charging it just before I go to sleep.
I'm wondering if in the long term that charging nightly even if the battery is half full. will damage the battery, as in deteriorate it over time.
The rule with Li-Ions batteries is to charge frequently without letting the battery drop too low. Doing a 'full charge cycle' will do nothing, these batteries do not need priming, nor will it help.
I really recommend BatteryUniversity for all battery questions. They do their homework and show their works, I listed them as sources on what I said above.

I did the same thing with my Galaxy S2,but i notice that the battery health is getting bad and it doesn't last like it used to. A few times wouldn't hurt but it might be bad for long term.Also the Nexus 7 doesn't have a removable battery so its best you don't charge it all night and unplug when it's full.Hope this helps
