First of all, hello to everyone. I have been reading through a lot of threads here in the last few weeks after getting my HD2, especially the ones about battery life.
I have never owned a smartphone, so I have no comparison but I'm barely getting through 1 day of use when fully charged! And I'm not even using it that much yet, Wifi is off, no data transfers, just some texting and calls. I have installed Bandswitch and Battlog, didn't really help though.
Got the phone brand new (T-Mobile US) and haven't done any major tweaking yet, it's still pretty much stock with a few programs that I installed so far.
Do you guys have a similar experience or is it completely different? I love the phone, but if I dont even get through one day of use (and I want to use the phone in the future, not just for surfing but for music streaming or web browsing), I would have to bring it back.
Any help appreciated!
It's just something you have to live with, buy a spare battery, or the extended battery, flash a lighter ROM, adjust screen brightness turn off push e-mails etc etc.
I can get 2 days battery from very light use. i.e. a few texts and calls a day, no Wi-Fi, bluetooth or internet browsing. That's just how smartphones are.
So how do you do it on a daily basis?
My battery is fully charged in the morning and lets assume I'm using the phone for what I bought it for - some music streaming, gps here and there if I need it, some web browsing, calls and texts etc.
I haven't even started using most of the features of the phone and my battery has died twice on my already while I was out at night.
How can that be normal or acceptable? I can't charge my battery every 6h...

Maybe you shouldn't have a smart phone? Battery technology is ****, it's a shame, but it's true. The only thing I can suggest is a spare battery, I carry one everywhere.
I generally watch an hour and a half of video a day on my phone, text, call, use the internet and I can still make a 9 hour day with 40%+ battery left, and just incase I am out and about in the evening before I have a chance to get the phone on charge I have the spare.
But with that said half hours charge from the mains will give you a good 30% topup I very seldom have to swap the batterys and I use a pretty juicy ROM.

or maybe not
Given his kind of use, 2 days should be normal. Right now I'm squeezing 3 days out of this battery, and that's only because I swap it out when it's at 10%, otherwise it could be a little longer... and a few calls here and there is not the only thing I did with it... it's still my work pda after all
Since it's pretty much stock, unless it gets better with time (the first recharging cycles are the worst) and even after a hard reset it won't get better, it probably is something wrong not software related.
Install battclock and check the standby battery drain, shouldn't be much higher than 4mA, up to 7mA could be normal, any higher than that, especially if significant, and you've got something wrong, and found the cause to the short battery life.
First off, buy a couple of cheap oem batteries from here...
Now, these eBay batteries have performed slightly better than the original battery...
Some of us smartphone users are so used to poor battery life we have power charging cradles at home work and car just to keep the charge up... And have spare batteries every in case of emergency...
I take my phone off the charger at 6am to go to work... My avg day is 6-10 calls, 20 reminders, an hour of UNO, an hour as a wifi router and I return home at 5pm with 50-60% battery life...
they are trying to make batteries smaller and thinner so they can make the phones thinner and smaller so battery life is compromised. But you do need to give it some time to settle in.
Back up batteries and cradles to charge them are cheap and an easy solution. So are extra chargers to keep at work, in the car, etc. Most people can charge their phone at least an hour during the day and that should give you all you need.
The only smartphone that I didn't carry an extra battery for was the moto q9c, because it came with an extended life battery. But on these phones, that probably isn't the best option.
So what did you guys do to improve the battery life of your HD2? Are there any specific programs (I heared about G-Profile) you are not supposed to use or did you guys just deinstall all the T-Mobile Apps?
If I can just get 1 day of actual use out of it I am OK with that. I just dont want to have die every second or third day if I use more often than normal...
Any suggestions or may tests I could do? I feel like I could stream music on Slacker for about 90 Minutes and the battery would be dead...
EDIT: Just did Battlog for about 15 Minutes, my phone uses between 15ma and 31ma when in standby. So where do I start, how do I find the culprit?
I love huge screen HTC devices and Im a power user, so my solutions for power issues are:

Software and the end-user are the cause behind battery drain. I've got 2.5days out of moderate use so I don't think it's the hardware at all.
Methods for testing battery consumption and proof it is typically software related
Hi,
At the risk of looking like I'm trying to hijack this thread, I started a discussion on this particular subject a while ago as feedback on my finding after reading almost all the threads I could find regarding battery use on the HD2. Lude219 is 100% correct, the issue is always software related (yea, I know there might be exceptions to the rule) and my phone was a prime example of that.
See the thread below that explains how to measure your battery consumption, has logs and screen shots from users you have high consumption and also people who have systems where battery life is more than 48 hours so that you can compare your results.

I'm also sure it's software related. My phone would use app. 2% overnight with all connections closed. This i tested over months. Then suddenly without me changing anything drastic software wise, it pulled 5% per 3-4 hours. So after going thru all the cleaning routines nothing helped exept a good "ram cleaning" . Somehow or other the phone starts processes over time wich consume alot of power. One would have to look into it with a process manager to find out what exactly it is. WinMo seems to be quite sofisticated looking at all the running processes. So my view is , keeping the system tidy might be the only way to save the extra power.This is where the huge diffrence to other platforms seems to be, it can take quite a while until you have configured your phone the way you need it. I am useing the stock rom 1.66 German
thanks you guys for participating and sharing your thoughts.
But now, here is a thinker:
Last night, I let my battery drain all the way to zero and then recharged it at night. The only other thing I did was installing BSBTweaks and Touch X Taskmanager. I also changed my Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before).
And I couldnt believe what I was seeing, I took my phone off the charger this morning around 8.30am and now at 7pm I am still at 84%!!! I did not use the phone heavily but sent and received a few texts, made 1 call and played around with it for a little bit. Similiarly to what I did in the beginning after I got the phone, but then the battery had almost died at 7pm!
I am super happy and hope it stays like that but cannot explain why all the sudden it is that different...
Hi everyone,
This is a very usefull thread, for me it is, thanks to everybody that answered.
regrding the last post, a noobish quesition is
”Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before): how do i do this?”
I remember stumbling upon this setting the day i got the phone and started viciously going through it.
Somehow it didnt store in my memory the path i went that day so i can try doing what the man sugested.
So if anyone can lay a hand, much obliged.
Regards
i lost 12 pct over night in 9 hours with my radio turned off last night and only gmail and texts were open...
with battlog how do i do the test so it stays in standby? it keeps turning the screen on and off when i run benchmark
You may want to flash a new radio. Try a new one each day and measure battery life. I use radio 2.12.50 and have had a good experience.
yeah but with my radio turned off the radio shouldnt affect it shoudl it?
i use blackberry to stream pandora radio thru aux for about 8 hours a day and it still has 2 bars left after that.
HD2 just sits there and kills the battery lol
what kind of phone is that when you have to disable all its functions every time you dont use it?
seriously this is called unfinished product or poor design, that is beeing sold to customers as a next best thing.
you guys can argue with me all you want. i heard many excuses from users advocating the companies. such as. if you dont like this than pay more for a better product. well HD2 is a better product, its a 500 dollar phone damn it.
but you dont realize that even the "better" products suffer from same underdevelopment syndrome.
companies spend millions on consumer research and consumers spend millions on **** they dont need every year. cows eat grass, consumers eat garbage made by big companies.
where are the better products? they dont exist because it became "normal" to have a faulty OS or for your phone buttons to fall off, or battery to explode.
companies worked long and hard to make consumers get used to the idea that garbage is just a part of life, and worked long and hard to minimize costs of production, and cut corners.
which corners?
the final QA testing that is not beeing done by a company, so they can release the phone 3 months earlier, the consumers pay for the phone and test it.
we work for the company and we pay for it instead of getting paid.
the phone breaks oh how sad ,
company takes note(dont use this cheap glue or the buttons fall off, get a lil more expensive glue next year)
so they use better glue and cut another corner and we buy another "new and improved phone" and this time screen goes dim oh dang not again...and it continues.
do you disconnect your car battery every night so it doesnt die? or when you buy a lexus do you drive with your AC off because it cant pull the car around when ac is on same time as the stereo?
I've had my Flyer a few months now and in the last few days the battery seems to be draining very quickly. I charged it full again last night and this morning it was at 88%.
I've turned everything off so just the bare bones of the device are alive and i'm using Juice Defender, and still no joy. It's only started doing this in the last few days so i presume the battery is on the way out very quickly.
I've let it drain to 10% and charged it, and it's made no difference.
I'm not going to mess about with settings and more waiting to see what it does etc...., I really just want to get a new battery and be done with.
Where can i buy a new battery? I've had a look on fleabay and no joy.
Any suggestions where to get one, part no. etc...?
Many thanks in advance

happened with me also....10% battery drained overnight...
what app is using most of ur battery?
sometimes push service in some free market apps drains a lot of battery and it keeps running even when app is closed... check running processes... well i uninstalled that app with push service and all became normal
Thanks for that but i've had a look through and it would seem that there isn't anything happening over night that i'm not expecting or that is being very hard on the battery.
I'm pretty confident the battery is the culprit here. Sourcing a new battery however is proving to be a problem. Somebody somewhere must be selling them.
I've just been on to HTC in the UK, they have a service centre not very far away from me and they won't sell me a battery or even give me a part no. for the battery.
Come on, somebody must know where to get one.
I think i might have found somewhere in China...
Battery - BG41200
3.7v - 4000mAh
If the prices were cheap enough how many of you would be interested in buying a battery for your Flyer.
Perhaps do a group buy?
i thought flyers battery is not user replaceable?
It's very replaceable and easy to do.
Here......

I'm going to have to look at getting a new battery sooner or later. It's getting to the point hat the battery is always running low by the time I get home in the evening or even running out. With pretty much the same use it used to be good for a day and a half easily. Flyer was purchase may or june 2011 so it really needs to last another 16 months or so.
Well......I ask again. If anyone knows of where to buy an internal Flyer battery please post a linky.
I posted this thread earlier today
"I just wanted to know what people are getting out of their batteries. I unplug mine around 7:30 am when i leave for work. When I get to work i turn on my wifi (rooted thunderbolt) and leave that on all day. I have the setting to turn wifi off (flyer) when screen is off. When I get home around 5:30 i switch to my home network and by 8-10 my battery is pretty much gone. Is this normal battery life or are there any tricks I'm not aware of that will help with battery. My wife has an Ipad 1 and she seems to get days of use out of it before she needs to charge it.
Also, I don't watch movies or video at work... most of my use is surfing, twitter and email."
I'm trying to figure out if what is normal battery life and If mine came with a bad battery. If so Yes I would be interested in getting a new one.
The Ipad battery has much longer life and is a much bigger capacity battery. The new HTC Jetstream also has a much bigger capacity battery as well. I think HTC have learned lessons on how much battery power these flyers use, but unfortunately have used Flyer owners as guinea pigs, rather like the first Apple iPhone but that had terrible battery issues as well although they've gotten better over time.
When my Flyer was brand new the battery lasted for ages and i couldn't understand what people were on about the battery not lasting for very long. So up until a few weeks ago my battery was doing fine and then almost within a day or two the battery started to run down quickly and has been doing so ever since. I've since loaded/unloaded new ROMS and done all the usual procedures for deleting the battery stats etc..., and still no joy.
I think the problem is with the battery not being man enough for the job at 4000mAh, and the drain is such that the battery is being worked hard since September last year (in my case) to a point where it is now progressively failing. I'm not so sure either that it's all that good in terms of quality.
Most of that time it has been charging from one source or another. If my Flyer isn't in the car or in the house it's not often being used battery only unlike most other people probably use the battery only a lot, so i can't understand why the battery is failing when it's not even that old.
This is a big issue with the Flyer and for what the device cost i would have expected a lot better. I think the Flyer in itself is a fantastic piece of kit that i will no doubt keep for a very long time as i did my XDA IIi but i never had problems buying another battery for my IIi. HTC will not sell me a battery, they insist i send the device to them and they will swap it but will cost about £50-£60 for the pleasure. I flatly refuse to pay that!!
What is required is a bigger capacity battery (6000-8000mAh) in the same packaging as the current battery however, i think for now i would happily settle for another of the same battery if i could just get hold of one.
So far it's proving an impossible task!!
Just to add: Once you've made sure there aren't apps being opened at startup that don't need to be opened until you're ready to use them, also make sure wifi/bluetooth, mobile data is all off when not required, and all the usual tweakes to make sure animations are off, screen is on the lowest brightness etc..., then there is not a lot more you can do. I don't know how much use something like Juice Defender will be as that only makes sure your data connections are off at night and other times you specify. I've tried it and it didn't help at all so i don't know what else to suggest apart from turning the radio part of the phone off completely at night if it isn't on charge.
If i leave my phone off charge all night, having fully charged first, i wake up in the morning and it's down to around 86-88% battery.
Hello, new guy here. Thanks for having me here.
Did a search for the issue, but none thread found comes close. I did an update on Monday (24.03.2014) OTA to 4.3. Of course it failed - forgot to do factory reset before that so what I got was famous samsung screen with blue LED on. Long story short, managed to recover. I had all the usual after-update-battery-drainage issues, but after tweaking and forcing shut a lot of stuff it is much better. Except for screen.
When I use phone with screen on, the battery level drops almost visibly. I would estimate it at 1% for 1.30 mins. What's more - when I use Google Maps Navigation in my car, the phone loses charge even when plugged to the charger (old trustworthy TomTom USB, rated at 1000ma). Slow - about 1 percent for 7-8 minutes, but still. Oh, and phone gets very hot then. With screen off (power button or automatic off after 30 sec) the battery life is awesome and it charges like a sponge. even with constant H/H+ internet connection, audiobook player with headphones on and of course phone services. Comparing to "before update" its much better. Of course it may be due to lot less freeware (read: adware), but it is better.
However, screen is a killer in this deal.
60 hrs uptime, 15h 15min on battery, 47% of it screen usage. Next is Device Idle with 13%. During that time screen was up about 5h total, of that 3h while plugged to charge. I also went through two audiobooks totaling 20 hrs, browsed net (heavy with the downloads - 3gb total) for 2h, used Kingsoft Office for 2h and navigated with google maps for about 4h, did about 3.5h calls, emails check every 10 min (just headers), some texts and camera. All times approximated, but fairly accurate.
Phone is 1,5 years old, is and always was stock. Bought in UK, used in UK, locked with H3G (Three).
Does anyone have some advice? Tips? Tricks? suggestions? Much appreciated.
Thanks,
Adam
What you have is normal, you need a new charger is all and probably a new battery. 5hrs screen on time from a full battery is the best you can expect..

Thanks for quick reply.
Well, since my SGS3 is 16 months old I would say that max screen for me would be bit less than 4h. Battery was used and abused (had message about it being too hot for charging a few times etc.), but right now it is more like 2h on scree time. And NOT charging while navigating is new. Started right after update. And this not charging issue is of supreme importance. I've a roving job over quite large area so I'm driving a lot. And sat nav is a must. And since it's draining battery even on charge it worries me as phone is used extensively - technical chats, calls, online and offline documentation etc.
Anyway, will change the charger. Battery... Have half a year till end of contract, so will think if I need the expense.
Oh, one more thing. On Monday my SanDisk 32gb SD died - that's why I updated. Wasn't sure which gave. I had unexpected unmount message with this card. Could this issue use more battery as well? different card now.
Thanks again.
Sd card issues will drain battery. Charging stops when the battery reaches 50°C so if you are navigating and don't point an air vent at the phone it will overheat and stop charging.
Batteries last six months before capacity is reduced, after 16 months you will be lucky to have 50% the original capacity, less if it has ever overheated.

Oh, that I know. I'm hard on batteries, but not in phones. None of my phones ever had failed battery pack, but laptops... all of them. But that's not the issue.
Battery is essentially low energy chemical reaction, so obviously it will be degrading. No issue there. That's why I'm not shooting for max parameters and not worried about it, especially since update phone lasts more. Waaay more.
I changed chargers and it's the same (I have two more never used TomToms and one Tortoise rated at 2 Amps). So i'm starting to think that the issue is not batter, charger etc. I think Google Maps on navigation (which uses simultaneously Screen, GPS and internet) also goes on max on CPU and GPU. that's why tere is overheating and not enough power for everything.
So it looks like software issue. Google maps in particular. Do another factory reset? Everything is up to date. Or maybe I overlooked something?
Partial solution found
Hi all,
Sorry for late update, but was out of the country and all that.
Thanks for suggestions. They were useful to solving most of the issues.
First, changed cables, not chargers. cleaned also contacts in the socket of the phone, so battery gets charged well and fast all the time. And is even better after couple of cycles of full discharge/full charge.
Probably because of having less "apps for free" it is simply phenomenal - normal sync (incl. emails), normal gsm, heavy music listening - takes about 5-7% of battery charge per hour, depending on signal strength. It is much worse when working with screen on, but still good - about 5-6 hrs of gaming for example.
There is still issue of excessive battery drain while using google maps, but this may be software issue. will be uninstalling/reinstalling it soon. Should help.
Will inform on that one as soon as status changes.

Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

Wow I did not know any of this. I will be following this thanks for sharing.
how long is the battery lasting if you are only going down to 50 and up to 90?
Gees! Below 50% really. I would tend to agree somewhat. I never let my phone fall below 20% and usually charge until 97% more or less. But 90-50. I don't want to be walking around with a battery back. I need my phone to last all day and 40% of the battery just won't cut it.
Xuck that !! I have a 3000mah battery for a reason if it goes then it goes ill most likely have another phone by then.Not gonna sit here to nickel and dime my usage that's not why I got this phone .
GM makes the Li batteries last in the volt and bolt 10 years by not letting the car drain the batteries more than 2/3rds down, leaving the batteries at 1/3rd charge. Tesla does it too.

Nah, I don't own my phones for more than a year so this doesn't apply to me. I'd rather keep using it from 100-1 just like I've been doing for years. I wouldn't be able to stand only getting an hour of use and charging it 3 times a day.
This battery information applies to all devices that use this type of battery be they Samsung or other brands. Its not just the Note 8. It applies equally to your Oral-B tooth brush! :laugh:
Ryland
this is a good habit to charge often at 50%. i usually let the battery run down to like 20% or less then charge. then when i have to go somewhere and i cant play with my phone anymore cus i worry i going to run down the battery.
Question are the "300-2500" charge cycles just as it says? I mean if I put it on the charger in the car for a 10 minute drive is that a cycle along with an overnight charge? If it is we should really only be putting it on the charger from the 50-90% with a guaranteed fast charge time of at least 30+mins to get the maximum charge cycles for the lifespan?

This was a really well written down to earth article about battery care. Thank you. I still have friends, family, and coworkers that insist on running their batteries to 0%. I can't convince them otherwise. Although my batteries degrade, it's never been anything easy shattering. Just notice an hour or two shaved of over a couple years life. As the article states, there is no way around this and I won't be a slave to my battery. In that note, I top off when I can.
My battery on my old phone tended to get to around the 40% at the end fo the work day, then I'd plug it in usually around the 20-30% and it still lasted 2+ years 'til I got a new battery. Now it's about 50% at the end of the day. But with Fast Charge, what do they expect people to do, plug it in for an hour, then unplug it, then go to sleep, wake up with 60% battery, go to work and then charge it for an hour when you get there?

Too black and white.
It is possible to offer some water resistance to a mobile that has a removable battery, S5 for eg.
In general such water resistance is small and is often abused by the owner causing problems. Hardly any owner reads the instruction manual that outlines what ones device can and cannot do, what the IP rating means in REAL terms etc
"Forced obsolescence" mmmmm, a battery can be changed in the Note 8. I understand your point though.
Ryland
this has been around for years. Doesn't make it very convenient to use nothing below 50%! I'd need at least an 8000 mh battery!! Therefore Samsung IS using too small a batteries in its top of the range device!

Totaly agree......
We then have to ask 'ourselves' WHY! Who forced Mobile brands to make anorexic devices? WE DID. We wanted thin small large wide slim ...........we got it and now pay the price.
I personally don't care if the device is thicker with a larger battery, for me its not a problem. For so many size was a major issue so the manufacture's listened and came up with these ultra thin mobiles that are vulnerable to dropping and breaking etc. off topic.
I find it totally bizarre that we spend mega bucks on such devices only to find we are educated to use them on software that reduces said mobile to the performance of a phone costing 100€! I may add many posters where disappointed when the Note 8 didn't have a 4k screen! Can you imagine the battery issues then?
Now we read this Samsung article and find we would need to charge our mobile several times a day as well as run it on a vastly reduced software programme. In reality that article is saying the battery is only operating efficiently at 40% of its total capacity before we start to degrade its life! Its all so absurd. What are we doing here folks?
Only one answer to this, either drop the performance OR vastly improve battery technology and fast.
Ryland
I'm not sure how usefull this is for the new samsung phones though, as the release of the S8 Samsung improved the battery.
Samsung Mobile R&D VP Bookeun Oh told me, "I focused on maintaining the durability of the battery over the long term, over hundreds of charging cycles. For example, after approximately six months of normal usage, the battery in the S8 will outperform previous batteries. While most batteries hold about 80 percent of their charge after two years in usual cases, this battery should be capable of 95 percent of its original capacity."

I am sorry but i will use my phone all day and charge overnight. If you can't use past 50% what is the point???? My pixel xl i have had since day 1 and use all day everyday and charge overnight and noticed no real decrease in battery life except a little change with oreo!
Outdated info and not necessary.
0% on your device is still considerably above what is considered the bottom line cell voltage before excessive discharge detrimental affects capacity.
A lot of engineering has gone into these devices to squeeze every possible mAh out of the packs, have a decent life expectancy AND operate safely. There is no need to strive for certain numbers and forcibly change your usage habits. There may or may not be a demonstrably better result long term but honestly is it worth worrying about?
And for removable packs...
Forget it. That's a thing of the past.
If devices had battery life like the Skyrocket, sure I see the NEED for a swappable pack.
But not now.
Having a sealed device makes it feel solid and keeps intrusion protection intact.
Holding an older device in hand, it seems almost laughable today. It creaks and groans and feels super cheap in comparison like some dollar store toy!
Hello everyone,
I'm not normally on the Moto Z Forums, but i currently (as the techy guy in my family) am faced with a strange issue. I have 5 people in close relationship (Parents, wife, husband of my sister...) with Moto Z's. Every single one of them is acting really weird. They all randomly shut down between 50% and 15%. After turning back on, they state anywhere between 1% and 5% charge left. On plugging the charger in, they claim 100% charger within under 30 minutes. Battery life between those 5 phones varies between poor and abysmal (sub 1h SOT to 2h SOT).
All those things aren't phone specific. Every single phone has shown any of those combinations. All of them are out of warranty. Since most of them depend on their phone daily without replacements at hand atm, i'm not able to spend days unlocking, flashing, rooting or the likes. I'm trying to convince my wife to let me factory reset the phone, but atm, she'd rather live with it then having to re set up 3 years of phone usage (i get that to a point. Not how i use my phone, but "normal" people are different in that regard).
I already read several thread around degraded Batterys, but this doesn't seem to be the case here. The biggest Problem are the random shutdowns. You never know when, below 50%, the phone will just turn off.
Additionally, two of those phones sporadically Have malfunctioning microphones. In calls and recordings they occasionally only transmit static noise. Usually that fixes itself within an hour or two (without any intervention).
I'm at a loss here. Any tips on what to try to mitigate those Problems? Since we're at a point where most affected are debating buying new phones, i'm willing give anything a try (as far as i can get someone to give up their phone for a day). Thanks for reading all of that.

Random shutdown is a common battery problem known in all types of lithium cell batteries (very common in used laptops), it's very common in Moto Z due to small battery(degrading is more visible) and overheating(degrading happens quickly)
However, the bigger problem is that some phones show 100% charge without the battery actually charging to 100%. To test if your phone is affected by this bug which appears in degraded batteries, simply turn off the phone when it shows 100% and connect the charger while it's off and it should show different battery percentage (for me it shows 96%), you can further charge the battery for 1hour while it's off even if it shows 100% and you will notice a much better SoT

what you're describing IS a symptom of degraded batteries. once the batteries start to go bad, the % indicator can't be trusted.
If you're a DIY sort of person, maybe this might be useful to you:
