wondered if people have an opinion on the best way to charge the XDA.
With my current mobile (samsung N500) I always used the policy of charge until full, then run until flat, then charge until full again etc.
ie, never recharging until it was flat. This is a bit of a throwback to when I used to use nicads a lot about 15 years ago.
the methodology being that if you did it this way the batteries remembered how much charge they were supposed to hold.
however, these new lithium polymer batteries in PDA's aren't supposed to have this issue are they?
On my samsung it's been fine, it's held charge well and never really gotten less, even after a years worth of charging and discharging.
A chap at work does the complete opposite, he puts his on charge whenever he can, whether it's flat or not, and usually before it falls below 80%, his reasoning being that he read somewhere that if you trickle charge it a lot it lasts longer.
as you can see, two conflicting methods of working.
what should I be doing to make my battery last as long and as well as possible
The "memory effect" issue is known for the N.MH battaries only ... and it's true that u have to drain it each time ... the XDA has L.Polymer type which doesn't have this issue ... u can charge it each night.
so I can charge it each night whether it's flat or not? sorry if this sounds dumb but I just want to make sure I understand this right,
don't fell like sending it off to have the battery replaced every few months because I abuse it.
yes ... u can actually leave it powered in the cradle the whole time
I knew the Nicads had the memory problem, but the NiMh aren't supposed to be as bad. Most new types of batteries don't have the memory problem, just increased capacities and less harmful to the environment.
discharge almost fully then recharge
I used to own a iPAQ 3630 and now I own an O2 XDA. Both the iPAQ and the XDA have a Li-Po battery, and with both devices I have the same charge/discharge experience. The battery lasts longer if you discharge it almost fully, till say 20-30% and then charge, not sooner. Constantly recharging decreases battery life considerably, as if the battery gets "lazy". My XDA's battery now lasts 5-6 hours usage with backlight on plus some 48hrs on standby. My 2 cents.
well after one days use I'm impressed by the battery life
fully charged and went off charge at 5pm
10 mins talk time
3 hours farting around with it in the evening
went to bed at 11pm
backlight off
no switch off set
phone switched off
by 7.30 am this morning, still had 30% battery left
nice.
Saving battery while listening to music
I have never had a problem keeping a battery charge until recently. I normally have my sx56 on standby and talk for about an hour a day and maybe spend half an hour checking appointments. I just recently got a 512 card and when I'm walking somewhere I listen to music. Maybe another hour out of my day. For whatever reason I used to end a 12 hour day with 40-50% battery and now I'm down to 10-20. I currently use wm player and keep the screen off when music is on. Do other softwares use less battery and is this drain in 12 hours normal. It sounds excessive to me.
doesn't sound out of the ordinary.
playing of MP3's really drains the batteries. quite a few reviews use draining the batteries by playing MP3's as some sort of yardstick.
I've seen reviews that quote the XDa as running down flat after 3 .5 hours from playing MP3's.
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.
Guys,
I have a sony vaio and i have a mode called Enable Battery Care Function where the app restricts the battery to stop charging at 80% which would multiply the life of a notebook battery (says Sony) there is another mode super care function @ 50%. I find this handy because i always have the power plugged in for my laptop.
Similarly i always have my HD2 plugged in to my notebook, so i keep recharging and may be over charging the device too and burn my recharge cycles. So can an app limit my charging to 80% or so? anybody share the same feeling?
Maybe an app can help.
Thanks,
Raj
commonsense would say it stupid.
stinginess would say it smart.
unless of course, you plan to use that phone for few decades where no more battery would be on sale. then you better start take good care of that battery.

Well,
I never use a phone for more than an year, you can see my list.. but what i do is to maintain it properly. I also have 2 spare batteries with me. so answer to my question if you know or pass.. this forum is no place for crap for someone with post count of 15.

A Lithium Ion battery should never be charged to 100% or fully Discharged. The famous 80-20 rule is applicable here as well, though in a different way. Charging to 80% increases battery life.
Don’t wait for full discharge, charge it frequently. Keeping the battery near to 80% always, gives better life. This is also what many vendors claim as “memory effect”.
Every battery has limited Full charge-discharge cycles. Of the order of 300+. In other words a typical phone battery can be fully charged/discharged 300 times. Doing more frequent charges, as specified in point #2, will increase overall life.
During first time use (when the battery is new) don`t use it till its fully charged. This is why it is always written on manuals “let the device charge for 2-3 hours”.
Best way to increase battery life is Not to use it. If you keep AC power plugged in on your phones, keeping the battery at 80% (as in #1), your battery will last longer. Though discharging it once in a month would be must in such cases.
Surrounding temperature contributes a lot. Colder weather gives better battery life. So make sure your cellphone doesn’t overheat, if it does, find ways to keep it cool.
When not in use for long, store the battery keeping point 1 and point 6 in mind.
Apart from this there are specific tips to elongate battery life which are related to user’s usage:
Keep the screen brightness to as low as possible. This can reduce battery consumption by upto 40%.
Don’t do heavy tasks like gaming when running on battery. This often uses High CPU graphics which drains battery faster.
Kill background processes that you are not using, multitasking is one serious battery killer.
Use headsets for long conversations. This will give you 40-70% improvement in talk time. Why? because when you hold the cellphone in hands, your body absorbs most of the RF.
Use software like WMLongLife, it can increase battery significantly. It does that by switching the network mode to 2G automatically when you doen’t require 3G

Well, I have my Sony Vaio TT92 with ext.batt (big one) now for 1,5 yrs in everyday use and until February had it in batt-save-mode 80%. It lasted about 10 hrs. with 50% screen-brightness and volume 50 %. Now in Feb it started to last only 7 hrs and less. Now I switched to full charge to get 9 hrs. of working time.
On the other hand I have my HTC Touch HD now for 2,5 yrs and until Dec. 2009 in full use, since my HD2 arrived as backup phone with a "xtra" sim-card so both the HD2 and Touch HD are ringing. I reduced e-mail download on my Touch HD to once a day and the batt after unplugging at 6 am shows still 98-99 % in the evening at 10 pm with the original batt that came with the phone.
What do I want to tell You: drain and charging cycles do not seem to affect small batts with little Ah-drain as much as notebook batts, so it seems to me.
For my HD2 I bought the ext.batt and it is fine for 2 days of full work with it. When I see it deteriorating I will buy a new one.
Or, more probable, the HD3
Kind of makes me sad though. The device feels good in my hand and I like it overall, but the battery performance is unacceptable for me. I went to bed with it having something like 93% (dropping from 100% after like 15min of play). Not even 6h later I wake up and when I look at it, the battery is already drained to 85% only from standby (Yes,always-on mobile data is deactivated, power efficiency is on). After playing with the unit in train and some browsing while commuting for 30min, its already at 70% or something. During the next few hours, while working, I was just checking mails, using whatsapp from time to time and writing a few messages. No surfing, no videos no games.
By 3PM the battery was at 15%. Even worse, the damn thing takes some 4h+ to fully charge. That's just too damn long, my iphone 3gs charges fully in about an hour. What is also very frustrating is that the Sensation discharges a good portion of its current as pure HEAT. Never saw a phone get this warm afer 15min of normal usage.
I knew battery wasn't going to be stellar but this just sucks. Most of all that a full charge takes 4h. fail :-/
EDIT: Ok guys the 2.3.4 update did the trick! The battery now chrages fully within 2h and battery life has ridiculously improved!
I took it off the cord around 8am this morning. Now it's 2pm and my battery is at 83 with some 46min screen time and slight usage. Also the heating seems to be gone.
Apart from that, everything runs smoother with the new update. Guess I'm gonna keep the little guy after all
However, I did order 2 extra Ankers + charger (25$!) as additional mobilty is never wrong.
Before you return it, I recommend that you call HTC support and request a warranty exchange for the phone and battery.
You may have a defective unit.
While my battery isn't stellar, I get a minimum of 10 hours before I drop below 20% life (always-on mobile data off, manual syncing, not too many widgets).
Your phone battery performance is not indicative of Sensation battery performance for the overall majority.
Most have said that the battery gets better after a few full charges/discharges, and the todays new update is supposed to improve battery performance. Many people say the Sensation is better than most other 4G phones.
I dont play games and such, mostly phone text and email and it lasts me a day and a half. There is also a better battery you can get.
That charging time is ridiculous, which leads me to believe that your unit and/or battery is defective.
Mine charges from 15% to 100% in 2 hours. Same for almost everybody elses phone.
You might want to reconsider and try warranty exchange mentioned earlier. Also, I would suggest the ChiChi battery. I'm running from 7:30 to about 4:00 with my WiFi hot spot turned on for my Galaxy Tab 10.1 and I'm using my phone for calls, texts etc., my battery still has about 30% left when I leave work.

Dude , custom rom and anker / chitec battery.
My first time with my new anker achieved almost 24 hours on battery and almost 4 hours screen time with quite alot of use during that time.
Totally destroyed my oem battery in every way.
Also I would do a Warranty Exchange and with the new update I have seen a big differance in 2.3.4 vs 2.3.3 in terms of battery life and speed of Sense in general. I purchased a Anker 1900mah battery for $10 and fully charged to dead I get on average about 17-20 hours and I would say I'm a good moderate to HEAVY! user. Switching back to a stock battery after calibrating with the Anker Battery has also improved battery life seeing that I get between 12-14 hours with stock now. I would charge to 100% go to bed and wake up with about 97%-98%

+1 I agree 110%, Try this though Calibrate the Anker Battery then fully charge your stock battery and see what battery life you get.

Get a anker battery and download leedroid/android revolution/insertcoin. I guarantee you won't want to return it than. When I first got my device I was thinking about doing the same thing but after I looked through the thread I saw people were getting better results with the anker or chichi. Don't be discouraged that its a third party. It actually out performs the stock battery and embarrasses it.
Also download calibrate battery from the market.

I had terrible battery life for the first week or so. 6 to 8 hours max, and 2 hours screen time if I was lucky. After conditioning the battery by fully discharging then fully charging on the AC adapter for a few cycles, it corrected itself for the most part. Yesterday I had 15 hours with 3 hours screen time and still had 20+ percent left. I have a chichtech battery sitting in my mailbox right now waiting for me to get off work.

After I got my anker I sold my OEM and got two more. I also have a evo3d battery that I haven't used. I also have been hearing good things about it.

really appreciate the good advice guys, thanks. I have done my bit of reading here and many many people here report having around 4h charge timr (http://forum.xda-developers.com/showthread.php?t=1154780)
So you guys can not confirm this? If so, it might be my battery is faulty. I will upgrade to 2.3.4 and calibrate. Probably will improve battery time, I doubt however it will reduce the charge time...
Something is definitely up. I just got my Sensation 10 days ago and am still stock. It takes me ~2 hours to fully charge, and that's with me using the phone like crazy while its charging....and the phone light on the entire time.
And I get a good full days use out of it....sometimes 2 days if I dont use the screen much and just phone text email.
IT'S ALIVE!!!

Also check if your phone is always awake because I had this and it had a huge affect.
I easily get 16-20 hours with LeeDroid's ROM.
i had the same battery issue with my first sensation. Even after several cycle of charging - discharging, battery calibration, the battery would not last for more than 7-8 hours. i exchanged it , for first couple of days, it didn't hold the charge for long,.but after i did battery calibration and update to 2.3.4, now my battery will last for 12 to 14 hours with moderate use. doesn't get hot with normal use, but over the weekend , i use map navigation and temp reached 48C. I think, i should not use it as GPS for longer than few minutes, or it may burn the phone.
Juice Defender Ultimate is definitely worth the tiny amount of money it costs. Just got just over 3 days on my Sensation, admittedly i hardly used it.
Usually i get a good 22 hours from it with medium use.

Just replace the battery and you will see the difference.. my phone last ast least 10 hours.. its just amazing....
I lose almost no charge while it sits on standby.
I work 12 hour shifts, I listen to Music the entire time, browse, login to home computers for about 30 minutes using Teamviewer and keep up with RSS feeds throughout.
By the end of shift I'm down to 5%.
Sounds like you need a replacement, rather than a return, bud.
I recently bought a Google pixel that appears to be suffering from excessive battery drain. I'm returning it, but am curious as to what sort of battery life I should expect.
I did an experiment. I fully charged it, and then just used Google camera to record video. I left it on the table, and came back sometime later.
It was losing charge at basically 1% per hour. In the 45 minutes of recording time, it had dropped by 46%. I used better battery stats to validate that no other apps were doing anything significant.
I'm hoping that they replace the battery, and if they do, what sort of life could I expect when taking video?
In general use scenarios, the battery does drain fast. The best I can hope for is 18 hours with less than 3 hours screen time, and sometimes even less...
