Hi!
I have had my Tytn for roughly 2.5 years. This autumn/winter the battery time I could get out of my Tytn was really ridicilousley low, so I bought a new "non original" 1500 mAh battery. It got better but not much, I started to think that perhaps the battery time was never better than this.
The other day I skimmed through this forum about battery problems and found this little program for meassuring battery consumption. I have now had it on since I removed my phone from the charger this morning and now, 4 hours later I'm down to ~30% battery power and acbPowerMeter tells me that the phone has used 90 mAh all together.
I have made 1 shorter phone call and made a couple of synchs with turbo 3G during this period.
Does 90 mAh sound at all right? That would mean that the battery was crap to begin with....or is it possible that acbPowerMeter isn't giving me even "close to correct values"?
Does anyone have any comments or ideas around this issue?
Best Regards,
Olle
Don't know anything about your abcpowermeter. What I do know, is that when I've had a new battery, or when I flash a new ROM, I often have problems with low battery. I just run the battery down like three times in a row, and my battery always improves.
So before making any determinations or using a program, I always run the battery down.
I've got acbpowermeter on my phone, and I don't think it's much good to be honest. If I remember correctly, the last time I left it running, it severely drained my battery - not exactly what you want a power meter app to do.
I find it far more reliable by using BatteryStatus from chi-tai.info and just seeing what the momentary power usage is. (it sits on your Today screen). Yeah, it's not a comprehensive breakdown of your power usage over time, but it doesn't run the battery down like acbPowerMeter does
Like you though, I'm still curious as to what exactly my device consumes in terms of power over the course of a single charge, and I'm on the look out for a decent app which just ticks away in the background measuring power drain...
Hi!
Regardless of Acbpower I just bought a new HTC Original battery and now I have the "normal" battery life I was used to during the first year of my device. As it has allready been discussed in other threads: These non-original batteries are far from always a safe purchase...
Br, Olleman
I recommend Lion Batteries. I have had a great experience with their 3000mAh battery for over a year and a half. Use that 3G on my Hermes and music all the time -- serious user-- and the battery still last me over day. Mind you I am constantly on the internet and always using push email and other data-centric services.
As far as Battery Status, for general purposes is great as I find the more complicated the app the more drain on the system it is trying to read. A simple app that you can just keep an eye over a period of time I think works best.
As far as batteries I was concerned where to buy one. Since my brand new battery died over just a year. Mind you a tethered a lot and I think that tends to kill the battery life faster.
i spoke to htc about the abysmal battery life, they say that there could be extended batteries in the near future, with a new back cover (with the back sticking out)
i dont mind charging it every day but
everytime i do something basic, for couple of minutes, it goes down by 1 percent, everything is turned off, gsm 2g mode, etc.
anyway the guy at htc said its due to the massive screen, this is what drains majority of the juice,
For what this device has and what it can do the battery life is pretty good, if you just use it for a few random pics, bit of browsing, bit of music and a few calls you should get a days use, if you sit there for ages messing with it its gonna drain.
Im pleased with it myself, apart from the bugs, but waiting......
It's killing you literally? Step away man!
I find the battery life on-par with other smart phones I've owned. I use a desktop cradle (well should soon be using a desktop cradle) and an active holder in the car, so I find the battery keeps up OK with a typical day's use for me. The biggest battery killer is when the screen is on full brightness so I find essential to have the phone on power when I'm using the satnav.
I had really high hopes for this thread when I read the title. Needless to say, I'm pretty disappointed.
Where's the death I was promised?
Die and prove it.

To be fair most smartphones drain their batteries pretty damned quickly. Disconnect your data connection when you're not using it and bluetooth too. OK so you won't get weather updates but you'll save battery life. Just charge it nightly and buy a car charger if you really drain that sucker!
Wow, I think battery life is good considering the screen, better than I expected.
Currently, with screen set to 70% brightness, push email on 0800-1800 with hourly retrieval outside those hours, hourly weather/Twitter update, automatic Quick-GPS almanac data update, I last all day (~0700 to 2300), and still with about 20-30% headroom with the following use:
Push email as per above settings
50 minutes GPS tracking
50 minutes bluetooth on (heart rate monitor)
1-2 hours listening to music
Around 1-2 hours high-drain use (screen on, using cellular data/WiFi/GPS - for example browsing/app use/gaming/watching video)
30-40 SMS
15 minutes calls
One simple little trick that I learnt some time ago to preserve battery life is ..........turn down the brightness of the screen display. The brighter it is the more juice gets used.
Get the screen to turn itself off after, say, 30 secs of use. That also helps.
The rest, such as killing off data connections when not in use, etc, you already know.
It never ceases to surprise me at the number of negative comments re battery life. The impression I am left with is that if the battery does not last at least 2 months between charges, even though it is being hammered to within an inch of it's life, then that makes the battery performance rubbish. Anyone ever heard of a battery charger?
It's a really easy to use piece of kit that comes with your device that can be plugged in at night when you are asleep, leaving your device fresh for the morning.
Amazing.

What the heck do you expect from such a phone? The energy management is kinda good and it's the display that kills battery life. You have to get use to it. At least my Touch HD seems to last much longer, but I would never change back.
If you watch a video your battery capacity drops quickly. I estimated 4,3-4,5h of HW-acc WVGA video and 3,5h with a non-HW-acc VGA video. Not that much but it really looks fantastic.
My Solution for this problem is: second battery, extended battery and/or load the battery whereever u can. My normal usage drains 30% of the battery a day, so I get 3 days of normal usage (I'm not an excessive handy user). The standby duration is with 300h not that good, but yeah that means still 12,5 days of standby if I calculated correctly.
The point is, that the phone is that good that I'm attracted to play with it and then the battery life tends to last just a day or less.
I bought a second battery (~22€) just for longer rides. I think it's ok.

EEK!, don't come on this forum and complain about the HD2! not allowed. this is now the official HD2 Appreciation society, don't ya know.
I recommend instead you buy some lube oil, massage it into the device, light some candles, play a bit of Barry White, and all will be well.
Then come on this site and reassure all the sensitive souls here that it is indeed the Holy Grail of mobiles and admit you are a Troll for finding a fault with it, and daring to ask about why it does not preform as it says on the tin.
And final advice...In the words of legendary Basil Fawlty... Don't mention the War !..or in this case, the Keyboard!!, I mentioned it once...and thought I got away with it..but no.

Exactly !!
1000 Mhz this bugger does.
And really its more then just a phone. with the battery cunsumption like wise.
But they told me one thing,,. something that Noone does
When you get the HD2. Its battery got 20% juice init.
Thats not for fun of the company (prolly sanyo) was laizy and dint bother to fill em 100%.
You have to charge the battery 6 to 12 hours and to peeking at your new jewel.
And i know Noone ever does that. But it ensures batterylife and eficiency
Here is the article >>
Initialize a new battery. New batteries should be fully charged before their first use to obtain maximum capacity.
Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours.
Ignore the phone telling you that the battery is full--this is normal but is not accurate if the battery is not initialized.
#DO NOT fully discharge a lithium-ion battery!
Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them.
Instead, charge them when the battery meter shows one bar left.
Lithium-ion batteries, like most rechargeable batteries have a set amount of chargers in them.[1]
2Keep the battery cool.
Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature.
In addition, check the battery while it’s charging. If it seems excessively hot, your charger may be malfunctioning.
3Charge your battery correctly, in accordance with its type. Most newer cell phones have lithium-ion batteries, while older ones generally have nickel-based batteries. Read the label on the back of the battery or in the technical specifications in the manual to determine which yours is.
Nickel-based batteries (either NiCd or NiMH) DO NOT generally suffer from a misunderstood phenomenon known as the "memory effect." As described in Wikipedia and many expert sources,[2] the term "memory effect" has been widely mythologized to describe any and all deterioration of NiCd (and other battery chemistries), in many cases misleading consumers into further shortening the lives of the batteries through over-discharging to "recondition" them.[3]
[This section formerly read: If you charge the battery partially enough times, eventually the battery "forgets" that it can charge fully. A nickel-based battery suffering from memory effect can be reconditioned, which requires the battery to be completely discharged, then completely recharged (sometimes several times). The appropriate length of time between reconditionings varies. A good rule to follow for nickel-battery cell-phones is to discharge them completely once every two to three weeks, and only when you have a charger available. [4] ]
Lithium ion batteries can be preserved by careful charging and avoiding storing them at full charge.[5] They do not require "reconditioning."
Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.

It's a shame most powerful mobiles heat up like nobody's business whilst on full chat these days.....there's no chance of keeping the batteries cool! Still, it's an expendable item and at least you can buy a replacement.....none of this iPhone 'sealed' tin rubbish.
while i find the battery life reasonable with the features this phone has (read screen size, processor speed), it will be nice to get the CPU throttling app another thread is discussing. don't need that 1000MHz running everytime i pick the phone.
On the same notes, how can i check if automatic screen brightness is kicking in?

Stick the phone under a bright light such as a desk lamp and cover the light sensor with a piece of paper.

are you the first wm phone user? Do you have good experience with phones that has so much specs? Do you use wifi and browse with phone very heavily? If you do, it is really normal that the battery will drain. My Touch HD does the same, it can last a day or 2 or drain like water not more than half a day, it depends on your usage. Try to get a second battery, or even the third one like I do, what is a big deal? It is completely normal.
I don't have a lot complaints on this phone as it meets most of my requirements.about the battery, I seriously don't think it is that bad. for example if you have a car with 1500 horse power and expect it to have or rather 30-40 mpg, don't think it is possible. try to use your local gas station (in this case your friendly charger) more often.move on with your life please.

That might be a little difficult because this battery problem is killing him, LITERALLY
Some say let it drain all the way, then fully charge...some say don't let it drop below 50%...i tried searching, but couldn't get solid info....so what really is the best way to charge a battery in order to get maximum battery life? thanks
Lithium ion batteries shouldn't be fully discharged on a regular basis; they prefer partial charges. It's useful to fully discharge occasionally however so that the phone knows the full range of the battery's charge states or the battery meter will be inaccurate.
It might be better to discharge to some particular level than another, but that's impractical. Best practice as far as I'm aware is to charge whenever possible. At least we have user-replaceable batteries if they do start to get weak!
Yes, 20%-40% drain is ideal balance of long-term battery life and not changing too often. Of course, the lower end of this would mean about an hour of use if you have the display on the whole time. So, best thing for the long-term life and ability to use your phone cord free is to own 2 batteries and change when possible.
I don't even bother to "calibrate" (run the battery down 100%) because I switch it often enough and I don't need to know if I have 40% left instead of 55%. If I have high use or only one battery on me then sometimes I'll let nature run it's course, but I never go out of my way for it.
Well in all honesty, I have to say that I've been doing the complete drain and full recharge for about 5 - 6 cylces since I got the phone about a week ago. Furthermore, I have set my autokiller to aggressive and I've seen a big improvement in the battery life. i.e. from 23 hours to about 1d and 20 hours.
hi there!i am new to XDA. can anyone of you guys help me out with my battery problems.
I have a asus P320 windows phone . it shuts down itself when the power is still 70% . is there anyway to change the registry settings to prevent the auto shutdown due to low battery. i would'nt have bothered with this shutdown if the battery was old but i bought a brand new battery , and no matter what the ROM is it still switches off . I would really appreciate if someone could help me on this.
is there any way to change any of the registry values to disable the lowbattery warning and the autoshutdown.
The battery is not truly measured by "capacity". The capacity is derived from measurable data, mainly the voltage. The voltage for new batteries is very little depending on the load which is applied to battery. Over time (and charge cycles) however the chemistry in the battery is aging so that the load on the battery lets the voltage drop when load is applied. Load is anything like the CPU demand, lights on and so on.
So for your case it is highly probable that idle the battery shows 70% but when load is applied, the voltage drops below the shut off point and the device is off. There is no option to adjust this - it is hard-coded in the battery driver.
Have a look at my battery measurement thread linked from my signature to get some background and find a method to track this.
To give you a rough hint: fully charged, the device should be able to stay on with LCD light (fully lit) on for several hours. With what you report it should go off within less than 2 hours from my estimate.

Thank you for the quick reply. well, the battery does'nt last much time though . i tried to discharge the old battery (which i still have) to 0% and when i charge it for some time and switchoff the charger it shows some % of batter left and after sometime it shutsdown showing lowbattery warning.
I can understand this happening @ 5% or even 15%but @ 60%- 70% on a brand new battery is a bit much.
if only i could just prevent the autoshutdown, in the mean time i have to check on your battery measurement thread/
From my battery thread I have linked some info on battery chemistry. Bottom line is that LiIon batteries are aging from the day they are produced and the dependency on charge cycles or discharge depth is minimal (different to older type NiMH batteries). So even if you buy a "new" battery in the shop it may be 5 years old from its production date already.
My experience with after-market batteries (so non-original) is very bad. You almost never get good quality and usually old original batteries perform better. I have lots of batteries checked on the Typhoon/Hurricane/Tornado and several on Vox/Excalibur. Especially the true original branded like Sanyo, Celxpert or Samsung have sometimes exceptional performance. I have some of these that already have 5 years (of little to modest use) and still have their nominal capacity. Recently I bought an original packed battery for the Qtek 8310 (Celxpert) which should be 5 years old - and this one has its original capacity! On the other hand I have also bought cheap Chinese that have only 30% of the labeled capacity.
Hello,
I read in the internet that is not recomended charge 100% the phone's battery. It's about the battery life. I want to know if it is really true....
Sorry my bad english :cyclops:
Maybe if you want to keep the phone for 5 years you'll notice a difference in battery life by keeping it charged between 20-80% but rarely does anyone do this.
True? Yes, it is. In the same way that it's true that a (properly done) overclock on a CPU will shorten it's lifespam. Yes the overclock will shorten the CPU's lifespam, from 20 years to maybe 15.
Your battery will degrade regardless but by the time it becomes an issue, you'll probably have moved on to a new phone anyway.

The theory behind this apparently is that how battery likes to be in certain battery levels based on the voltage.
Based on what I understand, the phone/battery likes it better if battery is not less than 20 and not more than 80.
This means that if you charge between 20 - 80, you can have a lot more charge cycles as compared to 0 - 100. This could also mean that the battery can last longer in terms of longevity.
But as mentioned, not many people does that unless they are looking to keep their phone for more than 3 years.
These are based on my limited understanding and my own experiences.
You can google battery university if you need more info.

Most of the information here is correct I have an am always doing battery tests research and such
80% and 20% are the magic number for maximum overall life of a battery...
Also no on mentions heat and cold also degrades the cells inside
I also recomend if you make it through the day shutting off fast charge......
If you think about it it is simmilar to any other battery,
Take a car for example I know i know lead battery vs lith ion but slow charging is the best method for any types of battery life in the long run.... it does not excite any of the ions as much as fast charging......
Fast charging on auto batteries is what we call a surface charge it quickly excites the electrons for a quick zap of juice but then over all that spreads out among all of the rest of the electrons quickly draining and shortning over life....
Slow charge generates less heat as well as does what we call a deep charge....Which is better of coarse I have had automotive batteries say like in my eclipse its 9 years old and it was a 800 amp battery and even after 9 years now
It retains over 650 amps on battery tests because i slow charge it once a month for a couple days be it need it or not..
Also if you guys are over worried and snap dragon try part cyborg rom the engineering kernel used by samdung only allow for a 80% charge.....I get more screen on time than stock on less charge because it is optimized so well....any where from 6 to 8.5+ hours and that is more than enough more my needs....
Also wireless chargers generate heat which degrade life on batts cells.....
I can get way more into detail on any of these if any one wishes

Have just started reading about s8 stuff and have not rooted yet. Does the kernel allow you to set maximum charge? I remember back on sgs1 specific kernels allowed this but haven't seen it much since then

no samsung preset it at 80% and since the bootloaders locked no way to modify it
Ahh I see. Thanks for clearing that up. Looks like since I'm on oreo now I'm stuck without root so I won't be playing with any of that stuff. Have a good one!
