strange battery meter behavior? - 8525, TyTN, MDA Vario II, JasJam ROM Development

i pretty its way too good to be true.
last time i charged my 8525 was yesterday, friday. and usually when i charge my phone overnight, by the end of the day, id get a 90% battery meter reading.
well today more than 24hrs after, i still have the battery meter reading at 90%! is this true or a glitch?
im not a heavy user of the phone though. and did not do anything outside the norm of my regular use.
anybody else having this phenomenon (?)

if u dont use the phone heavily and battery has been trained as in drained and re charged a few times then yes its possible. im at 90% also after a whole day but phone has been sitting all most all day today. its saturday so very little calls for me today.

oh ok... thats good news then.. ive read some incidents where battery meter reading was 90% and people think reading is good and accurate only to realize battery meter go down to 20% after awhile..
ill go see how it is tomorrow without me charging overnight..
i do have bluetooth on....

My battery can act strange at times too, but I am just trying to ignore it lately. I finally came to the conclusion that if I watch my battery meter all day long then how can I enjoy my phone? Buy an extra oem battery and never look back. I ordered one today.

Be aware, that changing location and so the cell location and needed consumption for the phone function maybe much less then at another location.
Recently a friend here from Germany told me, he was used to have an empty
battery within 2 days on his wizard here in germany. While he was on vac in Indonisia the same battery was alive for nearly a week. Hard to believe but obviously true...

Terrible battery life?

I'm currenly getting around 9 hours with little use and without the WiFi turned on! The only app I'm running is s2u2.
Any ideas? Is anyone else experiencing such bad battery life?
Thanks.
Have no problem with battery life.
Probably best battery life I have had with HTC.
Mainly calls, text, checking email and some web access.
​
My standby time definitely has gotten better over time! In the beginning I was lucky to get one day (would leave in the morning, and in the evening I had to charge again). Now I get a day and half, or maybe even two.
No problem with mine... after 2 full days still with 60%.
Watched an 1 1/2 hours long movie on my TP2 only used 5 to 10% on my battery.
That's strange. I get 2 days on a W910i on the same network with similar useage... I've not yet a a full day on the TP2.
The Vario V (TouchPro2) has the best battery life of all HTC's I've owned. Maybe it's your S2U2 settings?
Indeed, maybe it's S2U2. I know that when I first had the TP2, I installed almost everything I found, including S2U2. Battery life wasn't good at that time.
After a hard reset I paid more attention on what I installed, and since then (and after some charge cycles) it became much better!
I get ~ 2 days with moderate use. Ive bearly used it this weekend, its on its 3rd day and still at ~80% power. No problems with that.

Exactly my experience.
The firstday was horrible. after some hours it was nearly emty. but now a week later it is much better and at this moment this phone has the best batterylife from all my PPC's before!
so wait a week and charge it every night and it wel be better in a week ;-)

I took advice from a fellow member on how to charge it, 12 hrs the first charge, 8 the second, and batt life has been steady since then.
I've just been charging it till the light goes green, is that wrong?

Here is some advice i got when i pretty much said the same thing... Hope it helps..
na leave it on charge as thats a false full charge. leave it for another 9 for sure. then use it till it prompts you to charge again and charge for another 8. after that fill your boots, but occasionally let it fully discharge. hope that helps

What is 'S2U2' please?

Terry, East Grinstead, UK
Since the last time I charged it:
75 - 80% left
42 hours standby
4 hours active use
I too have varying battery life... Sometimes I get to the end of the day with about 20% left, others, I get there with about 35% left...
Have put it on charge at the end of the day and leave it till I wake up the next morning. Is that a bad way to charge it?
Also, are there any true task managers, which show all the running processes, so that I can have a look at what might be causing my battery to drain the most?
@terrypin
S2U2 is a programme called Slide 2 Unlock 2. Never used it myself, but it's available here...
have no problems with battery life. mine lasted 1 week with advanced use, some texting, wifi was enabled, i played bubblebreaker a lot (adore this game ), watched a few mins of some films.......
i'm very happy with it
My battery is just making my life miserable. It comes down to 50% in first two hours after nightful of charging. If I were to watch a movie, the battery just drains down even before the movie has ended.
Must have done umpteen hard resets as per the cust serv guys. But still the same problem.
I am now planing to get my handset exchanged for a new one. Hope that sorts it out.

Let me google that for you S2U2
...just be carefull to set OFF the digital battery in s2u2 settings!!
I've noticed digital battery option drains the battery...
...my suggestion is to set off every possible s2u2 info option... weather, appointment notifications, digital battery... everything OFF... the battery life will be much longer!!

Firmware version related to battery life?

Since there now seem to be a few different firmware versions floating around, shall we see if any of them give better battery life.
Of course we don't have an objective measure of battery life, but we cna get an impression.
My experience:
TMobile UK f/w 1.15.110.10
Battery poor - It needs topping up through the day or I won't make it to teatime, worse than my Touch HD which was 18m old. Similar usage, ie push email, Twitter sync, intermittent browsing, an hour a day ebook reading.
T-mobile UK same firmware
Battery fine, much better than my old G1, need to charge every other day (as opposed to everyday/overnight each day).
Uses (per day):
Push Email
Light Web browsing
About an hour of gaming
About 40 SMS sent
Twitter/Facebook constantly
About 2 hours of music usage - Spotify
Music using BT Earphones, Bluetooth on around 2.5 hours.
That's a big difference in battery life between you two, I wonder if there is a bad batch of batteries?
I think it has nothing to do with batteries or software. It's all about how the phone is used, what the signal strength is, etc.
Mine lasts two days on moderate use, but I charge it every night anyway.

I also have the matrix style live wallpaper running http://www.cyrket.com/p/android/fishnoodle.digitalrain/.
It may be worth noting that I no longer charge overnight, only charging when it's low and until it's fully charged (I used to charge my G1 overnight or basically when I was on the desk, it became overcharged, battery swelled up, would only last about 2 hours but sometimes it would last about 10 minutes).
I also have no problems with signal and am pretty much constantly on HSDPA.

how long full charge takes ? at what battery % you start to charge ur phone?
did you charge till full since you first unbox your phone?
I have my brightness set to half way and have watched a few movie clips lasting maybe 20 mins and have just done a bit of brief messing about and i find the battery drains to about half way after this.
I have not let it drain out yet but it does not look like it would last a day if i had to listen to music surf and do a bit of gaming.

My firmware is same but battery is brilliant for me, try using a power manager and maybe look at widgets draining battery. I'm not using any widgets and have net off when not in use.
I wonder if it's about signal strength. By far the biggest drain on a smartphone is 3G, and my signal is quite variable.

I've just came back from Austria where I was using the net a lot over there for various things and I can tell you now, the signals over there are top notch!
The speeds remain consistent and the signals never go down by more than by one bar.
The T-Mobile network works perfectly even in the Underground!
This I feel had contributed to my battery lasting so long the last 3 days!
I've already noticed more of a drain since being back at home today!

Maybe about 2/3 hours? Maybe more, I don't exactly time it.
I put it on charge when it starts blinking so less than 14%
Yes I charged it full when I got the phone but that was only for an hour.

I think if you continually charge from when you have 30-90% the battery will perform worse than if you charge it from dead / near dead. I have been charging my tp2 over night when the battery is extremely low and can now squeeze 3-4 days use out of it.

It doesn't really matter with Li-ion batteries. It is recommended to do a full discharge every 30 charge cycles or so for the gauge to recalibrate, but the battery itself has no "memory" effect.
There's no difference if you charge it from 70% or 15%

That must cost a fair bit on the data doesn't it?
I've found with my T-Mobile Desire that the battery is really struggling and I can't get it to last a day as yet. I spent 3 hours with a friend that has an unbranded one and I saw my T-Mobile rom'd battery life deplete faster than his doing the same things. I think the T-Mobile ROM needs an update asap!
Since my last post, my battery the last few days has been bad.
I've also noticed now that it will only charge up to 98% and will only go to 100% if i remove cable and put back in. Then only to drop back to 98% straight away after I have removed it and then drop rapidly.
On T-Mobile using the older firware. Have asked T-Mob if the Firmware is the issue.
My honest guess is that all you guys will see an improvement in battery life over the next few days. Li-on batteries do need a few cycles before they'll give best performance and obviously no-one here has had their phone for more than a week or two.
I'm sure as the phone is rooted/custom roms appear/htc release the kernel/blah blah improvements will be made, but if I were you I'd definitely sit out any changes made purely on the basis of battery life until you've had the phone a couple of weeks. If it's still crappy after that, then it's obviously worth looking deeper.
I'm on tmob contact phone with my firmware version @ *.11 think some ppl have *.10 so not sure if the ota update will come to me but I've found that if I turn everything to manual update and turn 3g off when not using it I can get 3 days out of it with about 1 and a half hours each day of general use. Before that it wasn't lasting a full day! What firmware is every1 on??

Mine is .10 - the Battery at first was really good, I used it abroad in first few days and was great, 3G was used everynow and then, but wasn't a drain like it is over here in UK.
Now i'm getting last few days were on charge it sticks at 98% and drops pretty quickly.
T-Mob have asked me to factory reset it today and monitor to see if any apps are causing the issue rather than the firmware.

My battery life

Hi, I am noticing that my battery life is very short. I have to charge my phone atleast twice a day. Last night I watched a program on my phone which was forty minutes long. After that my battery was already 60 percent about. However.now, in the morning, I woke up and checked one thing on the internet by 3g and now my battery is already 40 percent. Why is this .... I know that battery life on here is not good but mine seems worse.
Is anyone getting the same?
Thanks in advance.
Tell us your settings:
- Do you allow background data?
- Do you always synchronize?
- Do you enable data connection?
- Do you connected to the Wi-Fi all the time?
I swear my battery life is far far better since i put that Generic rom on, maybe the minor updates htc have released help battery life ?
Maybe the update will fix the battery life issue? We'll see when it rolls out on t-mobile handsets.
Other people have reported excellent battery life (mine only arrived today) and it seems to improve over time. How long have you had it?
I had mine 1 week today was originally on the T-Mobile rom and have had terrible battery life up to even yesterday, updated to the Generic Rom yesterday and it honestly seems to last longer now.

I was waiting for someone to report this before I did .. I too was originally on the T-mobile ROM and updated to the Generic ROM. I didn't notice any increase in battery life. In fact I didn't notice any changes apart from the minor T-mobile branding having gone.
Yesterday I did the OTA update and again didn't notice any changes. I did this morning though, in 10 hours the battery only dropped 4%. Of course the phone hadn't been used in that time and I have wi-fi and bluetooth switched off but I am sure this is a lot better than I was getting.
Maybe the OTA update has improved battery life. Let's hope so.
Hello again,
Is the generic Rom the Rom without the T-Mobile stuff?
How would you get that? And would that remove your warrenty / insurance?
How have some T-mobile people get the OTA update whereas some have not?
Have you realy found a difference with it?
THank you

Yes to without T-Mobile stuff.
You can download it in the Android Dev Desire section on here. There are extra steps to take.
It WILL void your warranty.
Anyone that got their phone direct from T-Mob will NOT have it unless they did it manually. And by that i mean manually flash generic rom then update.
I noticed my battery is better but it's only one day. And i never really had a problem with it. I charge once a day anyways.
Thank you for the help.
However I am unsure if I should get the generic ROM.
What are the other advantages?
Because there is not a lot of T-Mobile stuff on there.
If I got mobile insurance with T-Mobile and flashed the ROM would I be able to claim if my phone got damaged or lost?

Advantages. The phone is as it would come straight from the manufacturer. You will always receive updates for the device before Vodafone, O2,T-Mob etc would have them ready.
If the phone was lost then yes. If damaged...probably not but if it develops a fault you can always drop it in a drink and claim on he insurance...bit dodgy like!
My battery life story
So, I downloaded the brut Google nav mod the other day and haven't had a chance to use it until today. Took a journey which took about one hour, and made sure that my battery was fully charged before I went. I still hooked up the phone to the car charger though, to save power. One thing I noticed about charging the desire, however, is that if it identifies the battery as being already full when you connect a charger, the indicator light stays green, so doesn't top up even when you have been using it for a while. I noticed this about 20 minutes into my journey by which time the battery must have gone down quite a bit. Removing then replacing the charger sorted the problem and the Orange light indicated that it was charging again. By the time I got to my destination the battery was at about 50%.
On the return journey, I hooked up the phone again, turned on Google nav and set off. About 30 minutes into the journey I stopped off at a petrol station to grab some snacks, checked the battery and read 17%! Even though it was supposed to be charging the whole time!! I then got a message saying that the power from the car wasn't enough to charge the phone and I should attach AC power ASAP, which I obviously couldn't as I was in the car. I ignored it, got home safely enough, disconnected the charger and then watched the phone die .
Ok, so I was using gps and 3G which clearly uses up power and I guess Google nav is fairly processor hungry, but I would assume that having it connected to the car charger would be enough. Coming from a tocco ultra, I'm used to rubbish batteries, but at least that would charge up in a car.
Don't get me wrong, I still love the phone, but I just need to know if this is gonna be a regular issue, or something that can be sorted out with a Rom update.
Just for info, I've had my desire for nearly a week now on TMO using the old Rom. And, the car was Passat estate which is in very good nick, so I doubt that was the problem.

I would look if the charger really charges the phone or if it drains it also when not using GPS/Nav etc.
Reason I'm saying this is that I once bought a charger that actually drained the battery instead of charging it, while it worked fine on my older Nokia phone. I'm assuming the phone deactivates some power saving features because it thinks it's hooked up to a charger, but at the same time the charger is too weak to actually charge it.
I have not used branded rom before on this phone but the htc rom battery life is fine. Mine has been going for three days with usage fine

intresting my battery last a day
I just started charging 2nd time my battery and it lasted hmm since about 2pm till 15% at about 00.00 which is pretty much 10hours of heavy use. i did leave it on sleep for about 2 hours though and i left it at 25% and after that it had 25-24 % lol so if you turn all the updates off it will last quite a lot i guess
I rang up T-Mobile today (tech support) to ask about the lack of update considering the rom was behind the non carrier phones at the start and then an update too. They said they do work on them when they see a notable difference worth updating.
Anyway, I also said I was incredibly dissatisfied with the battery and how long it lasted and wondered if it could be to do with the ROM being well behind the stock HTC one. The tech support guy was excellent and very helpful. He said that with the type of battery in the Desire, you need to make sure you have it on a MAINS charger from quite low for a good couple of 14 hour sessions with the phone off. This builds up the charge for the battery and you should see a marked improvement. He said that most people don't bother to do that and as a result get poor performance.
He did say him and 4 members of his team have the same phone and while some of his team had battery issues he didn't. The main reason being that he had spent a few days not taking it to work and running it down in the evening then giving it three 14 hour chargers. He said that made a huge difference.
He also said if I was dissatified to a point of big frustration they would replace the phone or refund. Can't ask fairer than that

[Q] Best battery charging practices?

Hello all,
I hope I'm not beating a dead horse by asking this because I have searched this site as well as other places around the internet and there seems to be alot of information out there concerning how to charge your phone battery. But every time I read something, it seems to contradict the last thing I read. So I wanted to pose both viewpoints to the experts here in one place and hopefully get some clarification.
I recently got the Note 2 and am really happy with the phone. One of the biggest and most welcome surprises is the terrific battery life I have gotten so far. I am coming from a HTC Sensation and while I liked that phone, I always felt like the battery life pretty much sucked. When I first got the phone, it would barley get me through the waking hours of the day and that was only if I used it sparingly. Over the course of the nearly two years I had it, the battery life just got worse. I typically would leave my phone charging all night as well as in the car during the day if I had heavier use that day.
With the Note 2, I am seeing much better performance. I can easily make it through a whole day starting at 6am and by the time night comes still have over 50% charge remaining. I am not a heavy user but I have found myself using it more, trying to deplete the battery so I can charge it at night. My problem now is I can make it through one day with no problem but to make it through two full days may not work as well. I feel if I don't charge at night when its still around 50-45%, the next day I may need to charge right in the middle of the day when I need to use it or am not by a charger.
So my question is what is the best practice? Is it best to fully charge then fully discharge, and if so does it need to be a regular habit or just the first few cycles? Do I need to remove the phone from the charger once its fully charged or will an overnight charge be a safe option? If the phone is only at 40% or more is it ok to charge it? Are there any other battery management practices I should be aware of?
Thanks in advance for your help
dont read too much into battery charges...charge as you like...........at home, in car, connected to pc...........lol..........the battery will last for 2-3 yrs well...then if you feel it is dying, it has a removable battery.........you can always change the battery, buy a new one...they are cheap...
for ex:
you get ~1200 cycles if you charge from 40%-90%, but you will charge twice a day (2 charges a day will last ~400 days)
you get ~400 cycles if you charge from 10%-100%..charging 1 time a day will last ~400 days again

The above is the only proven effect on our batteries. The rest is handled by the battery itself.

Honestly ive always charged my phones however and whenever I liked. Overnight and at varying parcentages. Never noticed any battery degradation at all. My x10 battery seemed the same as the day I got it after 2 years.
I figure any detrimental effects will probably occur after 2 years of bad practice at which point most people would have a new phone anyway

[Q] Weird battery issue

Hey guys, just got the phone on Saturday. It's been awesome until today. I noticed it has been draining super fast. I put it on the charger and it would not charge past 89%, and at 89% it said there was 1m left until full. I turned off the phone and let it charge to 100%, but when I turned it on it almost immediately dropped to 90%.
What could be the issue? Do you think a simple factory reset could fix it, or should I take the phone back to Best Buy for a new one?
Edit: using the corded charger that came with the phone
This just started happening to me as well.
My phone will say fully charged, and when I unplug it will immediately drop to ~91-93%. Not sure if it's a faulty battery or what not, as I too have been using the wireless charger and block given to me with the phone.
I'm going to Best Buy during my lunch today to see if they have any idea and will update if there's any useful news.
that is weird. I haven't had the issue on mine, though I only charge with a USB cable (I don't have a wireless pad). From my rooting days, there is a battery config file that remembers things like battery charging history, so a factory reset might be useful, though it's a painful process to get a phone back up and customized fully after a reset.
Hopefully best buy has a better answer...though it might be as simple as replacing the phone, to which a factory reset might have been easier...
Anchor - how is the battery life on your phone?
I think my battery might be a defective one as I can barely get through half of a day with 1 1/2 hours of SOT - and that includes taking several steps to try to maximize battery life.
Just a quick update:
Stopped by Best Buy today and talked to a surprisingly knowledgable Samsung person. He said I'm the second person with an issue like this and believes it's a faulty battery, so they're going to give me a new phone.
To my knowledge this is the only explanation as my battery was lasting half a day.
Same here... I just got this phone yesterday and the battery drains very quick. I will return it and get the htc M9.

Final Update: Battery has been much much better on the new phone. Previously I'd be around 50% by lunchtime and today I'm at 85% with nearly the exact same use.
what was your usge in your previous phone?
