hd2 battery is killing me literally!!

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

Sudden Battery Improvement ...

I thought I'd write this thread simply to see if it can work for others.
I have read throughout this site that it's good to allow your battery to become completely drained, and then recharge via the power adaptor. Some people even suggest to do it 2-3 times.
Yesterday, for the second time since I bought the phone several weeks ago, I decided to allow the battery to become completely drained. I then charged it using ONLY the power adaptor.
Results?
Before, when in standby mode, no radio, wifi off, screen off, I would lose about 1% battery power per hour through the night while sleeping.
This morning I was shocked. My battery was fully recharged just before midnight, and when I woke up at about 9am this morning, I had lost only 2%. Yes, it said 98% charge left.
WOOHOO!
Anyway, I guess it really does help to allow the battery to drain and fully recharge a few times in the beginning.

I seem to read somewhere that Lithium-ion batteries don't have to be drained to be charged properly. Moreover, it's just okay even if you keep on charging it with the green light on, i.e. reached fully-charged level. Well, I myself just got the HD2 and am pretty satisfied with its battery performance although I haven't really monitored it closely. I just charge it whenever I can.

I recycle my battery about once a month and it really helps.

You are right that it's perfectly acceptable to continually charge the HD2. You can't hurt the battery. I'm just saying that I tried this suggestion (from many other threads) and it seemed to improve my battery situation. It may not work for everyone, but at least it's something.

Peter,
This is the way to treat batteries if you want to get the best performance out of them. There are numerous posts on this issue on here but it does not matter how many times it is mentioned, people still don't read.
What you get is a load of comments about how poor the battery life is without them going through the conditioning process that will get the best out of their battery, irrespective of what type of battery it is.
It is always advised that you go through several cycles of full charge and full discharge, preferably when the battery is new, to get best results, and to do this on a regular basis throughout the life of the battery.
Undertake a good deed for the day; spread the word!

You're right. I've read so many different opinions on this matter, including a lot of research on the Internet. There really does not seem to be any consensus on the matter.
One thing's for sure, I will continue to cycle through full charge and full discharge on a regular basis, perhaps once a month. In the meantime, I'll just top it off every day.
Thanks.

There is a more fundamental point to all this.
Its not the charging and discharging that makes the difference.
Its the working of the battery under load that allows the barry to achieve maximum capacity.
And constantly discharging/draining the battery will have a negative effect over time, shortening life span and usability.
Just charge and use as much as you can.

Strange that all previous phones I had I charged the same way - drain then charge for 12hrs first three times, and then drain / charge as I go - and battery always lasted satisfactorily to me ... I know it is a li-ion battery but for me it works every time and I am sticking to it until they invent better longer lasting batteries

What happens when you Recycle them tho Do you not have to buy another one as I see there not cheap.

I think he/she means re-cycle as in a charge/discharge cycle

I recently bought a HD2 and was reading very differing advice concerning teaching maximum battery capacity.
-do not let the battery go fully dry, it might harm it (source: wikipedia)
-cycle the battery, drain and fully charge a few times.
-charge as often and much as you can, the battery has no no memory, top it off as you like.
So,,,
I take it now, that the battery likes being used hard, especially when new.
Drain to 7% or so, recharge, drain till 7% or so, a few times.
So do not try to find energy saving mods in the beginning, but work it hard.
I noticed I get a huge battery drain increase when I set the screen backlight to 100 instead of 40. and what a nice display it is
So I figure thats nice way to get to know the HD2, to use it hard and bright, until the battery is 'conditioned' and I know what programs I love the extra brightness in.
I have not been able to drain the battery in a day of expected use yet, always had 23% left or so, which is almost a 4th..
Oh and sorry for off topic, but are any of you guys interested in the ebook reading capabilities on the device at all?
I use a free ebook reader called 'freda' on 'night mode' with black background and red letters, and due to the screen size it is so easy to use the HD2 as an ebook.
I snug into bed and read like 50 pages of an ebook and maybe drift off and the device will auto goto sleep too, if I go first.
It's great.

Found this: Maybe "training" the battery isn't such a great idea afterall

It's allot to read but got some good answers.

Like I said in a previous thread, there does seem to be opinions on both sides of the isle regarding "training" a new battery. My experience has always that it definitely helps. Every device I've ever owned with a Li-Ion or Li-Polymer, I've found by training it I get a bit more than the reported average battery life.
With my Vibrant right now, I have 35 percent left after being off of the charger for 1 day and 5 hours. This is with light to moderate use, meaning some browsing, some phone calls, some market downloads, about 20 minutes of gaming, syncing, and reading e-mails. Of course my mileage varies if use the phone more.

That looks about right even without "training" on mine. I probably wouldn't worry about it. One less thing to worry about you know?

Well, technically, both trains of thought are correct. Yes, calibrating your battery several times in a row will help battery life. But at the expense of total battery longevity. All full charge calibration cycles shorten the life of the battery. However, it is more annoying to have an inaccurate battery meter. So calibration cycles are a necessary evil.
Personally, I do a calibration cycle within a week of getting the phone. And then one calibration cycle every other month after that. I don't see any benefit to doing more than that. However, these phones are basically throw away after 2 years, so I am not sure that it matters much if you do it a whole bunch. Plus, the batteries are user replaceable. So it matters even less.

That's an interesting theory. Unfortunately it goes the opposite direction of my experience. My last battery lasted 3 years (I've quit using that phone, the battery is still good) and I deep cycle it every time.

It's not theory. It's the chemistry of Li ion batteries.

And in the end, if your battery dies out, you can just replace it, right? This isn't an iphone where the battery isn't replaceable.

Question in regard to degrading 6p battery

Hello to all,
I just purchased a brand new Nexus 6p that was purchased about two years ago directly from Google. The individual bought it but never even opened up the box so the phone has never been used or even turned on until four days ago when I got it. My question is this. Even though it's still a brand new 6p can the battery still degrade even though it has never been used before? My first thought would be no because the battery has never been used meaning no wear and tear to the battery even though it's just been sitting there unopened for two yesrs but then I got to debating this with myself and I just don't know the clear answer. Should I be okay in terms of the degrading battery issue since my battery has never been used before? Any help is greatly appreciated.

Battery degradation occurs through it's lifetime of charging cycles due to heat (and chemical changes within the battery). Since your device has not been subject to this, it should be like new. Note there are literally thousands of N6P users who have never experienced battery degradation (or bootlooping). We have 3 in our family and none have been affected. I suggest you just let the phone charge and discharge normally a few times before you start forming any judgement on your battery life or SOT. Install Accubattery and check the battery health after several deep charges. After several full charge cycles, Accubattery will estimate the capacity of your battery vs. a new one (3450 mAh). Enjoy your new 6P. It has been a great phone so far (knock wood).

I appreciate the clarification on that. I wasn't sure when the degrading process started on a battery was. I love you this phone. In fact it's my second time owning it and by far it's my all time favorite Android phone I've ever used. I'm glad to know my battery should act as new and I should be okay from the battery issues. I appreciate you explaining in detail to me about what to do and how to check my battery life. I'll download that app now.

Okay I just downloaded accubattey. Now once I charge it for a while I will get results about the health of my battery. What do I need to look for that's tells me it's good? Any tips on using the app. So indeed I never should charge past 80 percent? I always have charged to 100 percent so that's going to take some getting used to. Also I don't need to let it drop below 20 percent? Thanks again for your help on this. This is all new to me as I've never had to guard against a bad battery before nor have I ever had one. I hope my new 6p will be okay. So far it's seemed to have kept a good charge but I'd of course like to see it do a little better being that it has a 3450amp battery inside. There have been a couple times of times where it seemed to eat up battery life quickly but I found out I had some apps running in the background such as YouTube once where it consumed 77 percent of the battery overnight once but I have since fixed that. It hasn't happened again so I'm good there. Anyways just curious to know what I need to be looking for on the app. Thanks a lot!!

I've always charged my battery to 100% and will continue . I leave it on the charger at the office and home, all night long 24/7. When I leave the house I want to know it is 100%. One thing to note is that you should not take the phone off the charger until the APP tells you it is charged, not the phone itself. You will see current flowing into the battery sometimes 45 minutes to an hour after the phone says 100%. That, and let the phone drain down to below 20% first in order to get an accurate charge measurement. After that you look on the health tab for the estimated capacity. It will be provided in both mAh and percentage. Quick Start guide here.

So you actually charge your battery to 100 percent. I guess I will do the same since I'm used to doing it that way plus I want that extra 20 percent charge. This seems like a really good app. I appreciate you guys on giving me the heads up on it. I downloaded it to both of my devices which my daily driver is the axon 7 mini. That battery isn't the best so maybe this app will help me tweak that battery into keeping a longer charge. I like a smaller device to be my daily driver although for right now my 6p is my daily driver just bc it's new but after a couple weeks I'll swap back over to my axon 7 mini as my daily driver

Yeah, I disable that 80% charge alarm first thing. Accubattery is just a tool and it's just giving you an estimate so don't rely solely on it. I will say that after a few full charges it converges to one percentage value and for me that has been enough confidence that my battery is not in a degrading trend (so far). There are a few Accubattery haters out there but it's been a solid tool for me. Enough so to buy the Pro version. Good luck to you.

Much appreciated! Yeah I think I'm going to be fine in regard to my battery. I mean it's brand new so there has been no usage of the battery until as of about three days ago. I'm super excited to have gotten this unbelievable deal I got on my 6p. Never in a million years was I expecting it either. I got in touch with this guy by chance. There was never any intent on getting a brand new Nexus 6p for 150 dollars but by the end of our conversation that's what he offered me. Just a very generous guy.

Battery Health at 85%...should I change it?

Bought a used LG-AS993 and the AccuBattery app says that it's battery health is at 85%. So instead of a 3,300 mAh battery I'm working with 2,808 mAh. I'm wondering if there's a more accurate way to test it or if I should return it and get a replacement.
Any ideas?
Thanks,
DJ

I dont think AccuBattery is absolutely exact. See it more like a hint of the actual state.
My G6 battery state was 108% after the first charge, and quickly dropped to 96% after 10 charges. Even if the phone was brand new.
My LG G4 was quickly reported as 82%, even if i have an LG guaranteed original battery manufactured 4 months ago.
So no, i wouldnt change it yet.

I think you are right because after a year of relatively heavy use my battery is still as brand new which can't be right.

Also just keep in mind that an OEM replacement battery is approximately $10 on Ebay right now. So you can worst-case just swap to a brand-spanking new battery, assuming you are OK following directions for pulling off the back plate using a heater (see youtube videos for battery change LG G6).

I have noticed that the less you charge, the less accurate the battery health function seems to get.
If i charge only 20% a couple of times, then the health percentage will drop. And if i charge it from 25% to full the health percentage will rise again.
If the battery charge recommendations are followed ( 40% - 80% charging every time), then the health numbers seems to become more inaccurate.
Quite understandable since it is easier for the app to calculate the health during longer charge sessions.
But at the same time counterproductive since the best way to get a long lasting battery is to charge 40 - 80%.....
So.... forget about the health tab, just charge it to maximum 80% and the battery will last longer than the phone....

I think that's good advice, to forget about the battery health, for two reasons: 1) Why would you even trust the "health" judgment provided by the app, which is demonstrably unhelpful and imprecise, and 2) Why invite more worry and stress over the battery which decreases your enjoyment of the phone?
Maybe we could also discuss the general schools of thought about the pros and cons of worrying about battery health.
But overall I feel like you should weigh and compare the benefits of worrying vs the benefits of not worrying. I mean, the way I think about it, is that if you apply the absolute worst treatment and abuse to your battery, you are *STILL* going to come out in a better situation than if you try to worry about the battery health.
For example, you incur a definite cost by adding extra hassle to your life of trying to just charge to 80%. So you get all the hassle, but what do you gain for all that hassle? Have you quantified what gains you get, after 6 months, after 1 year, after 2 years?
The tiny gains you enjoy after 2 years are *NOT* worth 2 years of extra hassle.

Couldn't have stated it better.
BTW I have used AccuBattery on a new tablet that I have, and it also gives variable results that aren't very helpful.
So I agree. Just enjoy your device and don't bother with these apps, unless there is some real problem to diagnose
