NOTE: Fourth Option Should Read 16-24 Hours of LIGHT Use!
I see a lot of people constantly talking about battery life on here and how they are disappointed by what they are seeing from ROMs, kernels, or the OTA release.
I'm interested to see exactly what sort of expectations people have on the lifetime of their phone.
I've been fairly cognizant of my phone's power consumption and have done a lot to ensure I understand how I use it and what effect that has on its life between charges.
I understand that a first generation phone with the largest screen, the fastest processor available, the most processor intensive camera, with animated wallpapers, synchronization to various web services, flash, and borderline experimental next-generation wireless connectivity that can tether to multiple devices. To have all that on a unit marginally larger than my old Palm Pre and roughly the same battery size (1150mAh stock) is going to come with some compromises.
I tend to overclock, ROM flash, and beat the snot out of my phone on a regular basis. Therefore, I have a super gigantic Seidio battery that I absolutely adore. I found that even before that, I was able to get my battery life under control if I controlled my phone properly, so I'm not sure what the problem is.
Did some people just get bad phones? Are some people just being unrealistic with their expectations? What goals do you think people should be setting for the lifetime of their phone between charges?
Its an honest question.
I used to get almost a week out of an old motorola flip style phone (v500 something).
Everything since then has been downhill.
I'm not under the false impression that these new phones are going to last as long as the older "dumb" phones, BUT.....Id like to be able to get through the day without charging my phone. I keep my screen about 40% brightness, I'm usually in an area with good reception, I only sync my Gmail, I've calibrated my battery, etc. The only real USE my phone gets is texting. I unplug my phone at 5am and its more than half gone by noon. Not real great IMO.
I think this will provide valuable insight as to expectations for this phone. Personally I have used smartphones since I can remember and I was bread to expect a nightly charge.
It may be unacceptable to some that we have to "mod" our phones to get reasonable battery life, but I really dont have too many complaints. Out of the box, the EVO is running a 1gz processor and powering a 4.3" display. Not to mention if you're running wifi and various apps. I think some people are just expecting too much from these phones. Look at laptops. When my dell was brand new, I could get 2-3 hours of steady use before it conked out. The battery life our phones are getting, modded or stock, isnt really that bad. If you're unwilling to do some research and easy mods or buy a spare $20 OEM battery off eBay please dont complain about it.

A nightly charge is acceptable. It's when you have to charge 2-3 times a day from moderate usage that is a little out of hand... Understandable that with heavier usage, more frequent charges would be needed.

I want to power a small village from my phone please
I want my phone to last a day. And call a typical day something like:
- l/2-1 hour talk
- 12-24 text messages
- 45 minutes - 2 hours web browsing
- 2 hours music
My iPhone 3GS would do this without a problem, my wife's iPhone 4 might do 2 days like this. The EVO just barely does this.
But.. I prefer the EVO for enough reasons I just dropped $10 for 2 extra batteries and a phone-less charger on ebay, and keep chargers in the car and at my desk, and get it plugged in for like 30 minutes somewhere during the day. I rarely use the backup batteries, but it is nice to have them.
Totally worth it for a bigger screen, 4G, more open OS.

This definitely sounds doable. If you aren't getting that out of your phone, I'd reccomend calling support. I'm going to assume your dedication has already lead you down your own troubleshooting path.
My standard was set with my BlackBerry: less than 5% discharge rate per hour under normal use, and I am happy.

Hi Guys,
I actually have a HD7m but my dad quite liked the 4.3 inch screen and was now asking me to buy a similar handset. We went out and he was quite impressed with the Desire HD.
But the catch, when I researched online, I found out the battery issue on practically every thread and community.
Now my problem: He is an old man and can get cranky at times. Currently owes a Nokia C6 and is pissed with the touch screen. So is it wise to buy him Desire HD even with the bad battery life?
Or worse case scenario, I swap my HD7 for his Desire HD????
Should I go for it or should can you guys suggest something else equally fluid??
It doesn't have battery issues once calibrated. I have 1-5mA battery drain on standby, that's even when running MSN and CallerID2Voice App in the background. And I can still get hours out of it when using it. Just recharge it every-night. I doubt your dad will be a smartphone addicted guy.

Hey,
Thanx...no he isn't a smart phone addicted guy. But the battery was so obvious an issue, I had to ask the experts here. Also, what exactly do you mean by 'calibrated'?
I mean, I have been an Android user before, but not quite sure what calibration is ?
He is a simple user with checking some mails everyday, music and some websites may be...thats about it, HTC Sense and all makes no difference to him actually...
If its battery life your after, buy a Johns Phone, you get 3 weeks between charges.
After you battery has been "run in" and calibrated you will get at least a day with light usage. Remember this is a powerful smartphone.

The battery calibration concerns only those who are using a custom rom. (here's a short article with app that does it for you if you're interested). I wouldn't recommend the DHD for my own father. Whatever you do to it you'll almost always have to charge it overnight, with stock rom it could be even twice a day. This isn't a problem for smartphone enthusiasts, but for oldschool people (like my father) who think phones should last a week without charging this can be quite off-putting. The DHD is also starting to get kinda old already, so you might wanna take a look at some newer phones. A good alternative could be the Desire S, as it has almost the same features with a slightly better battery.
And to those who can't admit that the DHD has bad battery life I just have to say that the out-of-the-box battery life could and should be a lot better. To get it lasting as it should takes a bit of effort which shouldn't be required from a normal user.

Thanx so much...that was really helpful...albeit your explanation on battery life, I just wanted to add that he was in love with the 4.3 inch screen...and only HD7 is the other device with that screen size...So I think Desire S is also a good option...let me check with him...
Again, Thanx!
depend on what you consider a good battery life, some may say getting a day is good enough, but some define good as atleast 2 days.

Absolutely right. I'm tired of hearing people evangelising that the DHD's battery is fine. It patently is not. Even when you severly rein back the device's features (features which HTC flaunted to get us all hooked), one ends up with 25-30% at the day's end.... And if you have a 'heavy' day of calls/browsing etc, you'll have to top up to get through the day.
But I still regard HTC as just about the best of a bad bunch...
Ok, sorry to hijack this thread a little.
The battery is fine, there are no issues with the battery. Your problem with the battery is that its small. Before you bought the phone did you not look into the battery capacity? I did, I knew it was smaller than the Desire's battery. Out-of-the-box it will act like any other lithium-ion battery that is just out-of-the-box. That "bit of effort" , what, plugging in your charger when it requires a charge.
These guides to correctly charge lithium-ion batteries are largely mumbo jumbo (charge to 100%, turn off, charge again for 250,000 hours, turn on, drain battery, rinse & repeat). Just charge it overnight, when your asleep.
Any smartphone with comparable usage will last around the same time and require a daily charge. If you want a phone that will last days between charges, don't buy a smartphone.
If you turn off all the bells & whistles, use 2G only and use it only for calls & sms', just like a regular phone. It will last days between charges.
If you want a powerful smartphone with a large screen, and lots of features, your battery is going to pay for it.

I'm not sure anybody on this forum expects days of use between charges - we're not daft. What I expect is to not have power-saving mode kick in by late afternoon when I'm nowhere near a charger, and I've not used the thing particularly heavily.
It's not right to conclude that others didn't read up on the battery before purchasing. You have no basis for drawing such conclusions.
HTC marketed the DHD on the basis that it's architecture was such that it didn't need a higher-capacity battery to do its job. Based on the fact that I'd had pretty good experiences with my previous HTCs, I saw no reason to doubt this.
In any case, just because you don't mind charging your phone part-way through a day, doesn't mean that everybody else should be happy with that.
I don't Say ! ^^

That's why I said that there are "oldschool people" (like my father) who think the battery should last a week. I don't mind charging the phone every night, but there are people who can't cope with such a "short" battery life. That's why the battery life of the DHD should be taken under consideration when buying a new phone.

I didn't mean that the battery was bad quality or anything, just that it is a bit too small for such a powerful phone. And yes I was aware of the battery capacity and I don't mind, but again there are people that require more from their phones.
And the instructions to close connections when you're not using them and turning down the screen brightness etc. are plain stupid. I bought a smartphone so that I can get my email whenever and wherever and to enjoy the big screen and not so that I can receive emails only when I choose to and so that I have to squint to see something from the screen when the brightness is set to the lowest. This is just a couple of the features I need ofcourse, but for me it's important to always receive emails instantly and not only when I can afford to spend some battery on internet connection.
When I was still running stock rom I could barely get through a day at work (8 hours). I had mobile network on the whole time and the screen brightness set at about 50% (which I think should be used at 100% all the time to really enjoy the screen) I talked for about half an hour during the days, sent 10 texts and listened to music/played/surfed on the internet for about 3 hours in all. When I got home I had to charge it. This ofcourse is everything one could need, but there are smartphones with better battery life.
Now of ofcourse when I have a custom rom that's tweaked and everything there's no problem with battery life, but that shouldn't be necessary to do and it's quite a lot to ask just so you can have a decent battery life. That's why I was talking about out-of-the-box battery life.

If you want to receive emails and text, I find that GSM is fine for that. If you want to go internet browsing, just switch on to 3G.
Smartphones these days have basically a different definition of battery life to the old nokia symbian and similar phones of old. Those could go up to a week. Smartphones on the other hand are considered awesome if they can last 3.
I do have to say ultimately I think HTC sold the battery life a bit short on the DHD. 1230mah I think is really just making way for all the other top-of-the-line features that it had when it came out.
HTC have released a great number of variants of this phone now, all with better iterations of design and also with bigger batteries because of this.
1400-1500mah (or even above) I think is really what you need with a 4.3" display phone. 1230 would be far more acceptable for a <4" display. Although it can be made quite livable for a day or two with an excellent custom rom, I don't really think it's enough for a basic consumer using the standard rom. That and the speaker/audio out are the two biggest pitfalls of the DHD imo.
Sensation is now HTC's newest 4.3" phone which has a good 1500mah battery. I hope Sense 3.0 doesn't wear it down too fast!
Ultimate thoughts: Although it's a great phone, I think it's a power user's phone more than anything. You will definitely only get the best out of it by customising to it's best potential, which is also when you get acceptable battery life. If you don't, it really does seem a waste.

I had the same sort of expectancy out of the battery using it moderately during a day at work out of the box. However with custom ROM installed I have found the battery to last easily the whole day with the same usage and probably have approx 40 - 50% left after 15hrs on battery.
just my 2c

I am extremely sorry but I disagree with u completely. You are talking as if you buy an expensive car but dont drive it too much as it eats a lot of fuel. If you want to just drive around, why dont you just get yourself a mopet. The point is, i have bought an expensive car TO DRIVE it around. If I buy a smartphone and not use its SMART features, why am I buying it for??? If I practically shut all the reasons why I bought this phone, WHY the hell am I buying it??
There is an old saying that comes to mind that it takes guts to stay in the minority. If the battery is flawed, ACCEPT it.
Anyways, I have got my answer. Thanx for your reply nonetheless.
As everyone says depends on usage.
For one thing i went from 80mA down to 8mA just by updating the radio which came stock.
Now with a different rom and kernel I get -1mA on standby, juicedefender is also a nice app. The battery life depends on your setup though, I easily get 2 days of moderate use/music/games/calls etc.

Hey thanx man...But was just wondering, with very moderate usage, will it still be over in no time?
Also, the other thing worrying me is the memory card issue...I cant afford to lose one card after another once I buy an expensive phone, u know what I mean...
The battery life is acceptable with moderate use on stock rom, if you're a power user you will have to stay close to a charger
There's no memory card issue from the DHD's part, it's just the crappy "freebie" sdcard (samsung?) which comes with the phone that stops working. The people who are complaining that the DHD breaks sdcards are those who buy cheap, bad quality sdcards or get a warranty replacement for the original one, which will be just as bad. The solution to this is to buy a better quality microsd card (costs about 15€) if the original stops working. Mine's still working great though.

After receiving a replacement 'new' phone, and having problems with my SD Card from the very second it switched on, I complained to HTC about the issue and the man on the end of the phone admitted around 500,000 phones that had been dispatched has been shipped with KNOWN issues & SD Card incapabilities. If you went out today and bought a brand spanking new card, in theory the phone WOULD NOT and the SD Card WOULD NOT fail.

I don't mean to hijack you here mate, but you assume/claim that:
'HTC marketed the DHD on the basis that it's architecture was such that it didn't need a higher-capacity battery to do its job.'
Well I take it that you assume this on the basis that Leprechauns are real and are roaming New York city as we speak? If HTC were doing any market research at all, they would realize that even devices with smaller screens have a bigger battery than the one they have put into the DhD, including the Desire Z & Desire's batteries?
I remember when I was looking at reviews for the original Desire, as I fancied one, the main complaints were the battery life, and the fact people only got a day's charge on it. So I thought fair do's, big screen, big price to pay? If HTC had done any research, they would have realized that people wanted better battery life, a better quality screen, better sound quality?
You want to know what the real reason is behind HTC putting a small battery inside the Device? Well it's the fact that the entire thing was rushed, and I mean rushed? There's evidence of this in the build quality, the software, the placing of different things within the phone and also the bad batch issues HTC experienced.
The HD was leaked in September/October, it was released by November, this is not normal for any device that becomes 'leaked'. HTC used a bad screen, imported most of the software from the original Desire, obviously making edits to make it Sense 2.0, but you can clearly see they didn't change everything? If you set the Android Pattern Lock Screen, you can see that it doesn't fill the whole screen, the IME is the standard HTC one with some arrows slapped in at the bottom? They didn't even change the size of the keyboard?, this is more evident if you use the IME in landscape mode, its hard.
What sort of company places an Antenna in the Battery Cover? It's true, remove your Battery Cover and you'll loose all signal? Pretty risky move for HTC, seeing as the Battery Cover is VERY easy to 'accidently' break, and frankly your screwed then right? It's like they designed the phone, forgot the Antenna, then quickly though 'Where the f*** is this going?' and decided to place it there? In my opinion, and a few others, they did this with the battery, they made the device too thin, and in reality they just couldn't fit everything in. The Desire S which is slightly thicker, packs a brilliant battery. Problem solved.
The build quality of the phone, is not one of a £500 price tag. Some parts of the phone squeak whereas others just do not feel adequate to the pricing of the device. There again we live in a world where no matter how much you pay, something always seems to be wrong.
Sorry if I have offended any HTC lovers, all attacks on my and opinions against me are welcome, don't get me wrong, I love my phone and I can cope with charging the battery every night. Chao.
How to smart charge the Galaxy Note 2 battery
The way you charge your device is very important and it can affect your battery life a lot. Charging it wrong will make it drain quickly and the battery will also last less, requiring a replacement after 1-2 years of use.
To smart charge the Galaxy Note 2, you have to only plug it in when the battery is below the 10% level and never unplug it until it is 100% charged.
You should also know that when your battery reaches 10%, it will last longer than usual. To understand better, it will drain much slower from 10% to 0% than from 20% to 10%. So don’t panic if your battery level is low, because it can hold for a very long time, especially in standby mode.
Never use low quality chargers, because they can damage your battery hand even the device. Only use original Galaxy Note 2 chargers and try not to use the USB cable for charging your device. Always charge it in the wall socket, because the USB port power fluctuates and can damage the battery. Also it will charge much slower.
Battery maintenance
Usually the battery is the first smartphone component that dies, having a lower lifecycle. Though you can prevent this by taking care of it.
The best way to prevent it from getting damaged is to avoid pulling it from its socket. The battery has some golden pins that can scratch or get dusty, so if you pull it out and back in multiple times you can damage the pins.
In order to help the battery work the way it should, always make sure to clean the pins with a soft cloth whenever you pull it out. This way you will keep dust away from them.
When buying a new Galaxy Note 2 battery, make sure to get an original one, as other might have a lower battery life and can have a shorter lifecycle.
Increase Galaxy Note battery life by disabling features
The Samsung Galaxy Note 2 N7100 comes with tons as features, like we just said at the beginning. But nearly all of them are big battery eaters and you need to be careful when activating them.
The CPU and display drain a lot of battery, so make sure to setup the display to turn off faster. Also don’t keep it turned on when you don’t need it.
3G and 4G are the biggest battery drainers on a smartphone. You should only keep the 3G or 4G network activated when you use the internet actively. If you really need a permanent internet connection, then go for 2G, though this eats your battery too. The best way is to only connect to the internet when you need it.
Do not keep the WiFi,Bluetooth and GPS activated when you don’t use them. They can drain your battery very fast even in idle mode, so make sure to disable them when you don’t need them anymore.
Live wallpapers are also big battery drainers. They consume a lot of CPU and RAM resources and also use your display more intensively. So you should never choose a live wallpaper. The most battery-friendly wallpaper is a dark one, which doesn’t use any CPU resources and also doesn’t requires the display to be very bright.
You also have to take care what apps you install and always look at Settings > battery to see who drains the most battery. There are some apps than run continuously and prevent your device from getting into “Deep Sleep.” This is the standby mode that helps the device conserve very much energy. If an app prevents it from getting into this mode, you will notice a very low battery life.
Please let us know if you found other ways to increase the Galaxy Note 2 battery life. We are also curious for how long did you manage to get your device running between charges.
wow thanks mate quite a good one!
Thanks!
Also you should add that if you always need to be connected to internet then its better to keep connected through WiFi as it consumes less energy than using EDGE or 3G.

Thanks it's useful

1. Deep charge cycles on a lithium battery accelerate the failure of the battery.
2. The device can determine the type of source it's plugged into, computer usb ports are safe.
3. Non branded chargers are safe if they are quality made. You just need to stick with quality and 2 amp/ short cables for decent charge times.
Sorry man, but those 3 things you listed are some pretty big misinformation that can easily be verified.
There's nothing "smart" about doing a deep discharge if your trying to preserve a 10 dollar battery.
After installing the new rom..I charge my battery full..then remove battery stats then drain full to zero for cycle.after complete ..I use smart charge method..that is .when my cell battery below to 10 something like 9 or 8 then I connect charger .and really it helps me alot

Deep charge cycles are for avoid "memory effect" and It apply to old Ni-Cd / Ni-MH batteries. Don't apply for modern Li-Ion battery. There is much more chance that the deep drain affect negatively the battery of a GN2.
Li-Ion battery keep better performance if never going less than 50%. But the difference will be barely noticeable.
Personally, after several tests on my own, I don't bother anymore with that (I mean for the modern Li-Ion type). Sometime you have a great battery, sometime a crappy one from a bad batch. I have seen battery died fast after "by the book" charges cycles. And others seem to last forever, no matter how bad I maintained her (like my 2006's laptop).
Anyway, thanks for sharing, even if you are wrong on this one
I don't know if you're wrong or right because when you search the net about battery charging, you find everything and it's opposite. But I disagree on three points:
- The battery is beefy and you really have to work hard to make it last less than a day
- I bought this incredible phone because of it's features. If I have to cut half of them to avoid drain, why did I buy it?
- I dare say that most of the people who buy a Note 2 somewhere are a bit "Tech-Nuts". If you're not, I am, so I don't mind if my battery doesn't last two years because I'm not sure that I will still have this phone all that long.
And if I do and the battery is dead, I'll buy a new, genuine, Sammy one to continue.
What's it worth to live 100 years if you can't have a drink from time to time, maybe have a smoke or whatever? Plug your phone in or out and use your GNote 2 happy
Lol everything has its cost turn off everything to save battery what is fun in that I have a smartphone to use it and be happy with animations and display and games otherwise get a 3310 it is best

Speaking for myself I've always been kinda aware of the failure potential of these batteries. For instance, I tend to not leave the phone unattended during charging and also use such tasker profiles as to shutdown when charge below 5% or alert when charging above 95%. These latter measures and others are mostly to help with battery longevity as well as or rather my ocdness on this subject.
My only gripe is that I never succeeded in instilling the same 'respect' for battery in my wife.. Pre or even post-note she always forgets her tablet or her phone plugged in the charger, even when no one's at home, sometimes for days!
But this recent note7 'mishap' let me tell you, made me even more wary of the destructive potential of the batteries in our phones. Especially since most of my latest snapdragon devices (m7, z5) get very warm while performing various mundane tasks (syncing via wifi/lte, camera, games rendering etc), much warmer then the defunct note.
Did this event affect the way you use your mobile devices and how? Is there any particular strategy you use with this respect? Or do you rather think that the failure rate being so low it's rather silly to worry about it?

Nope, it hasn't made me change anything so far. I don't believe the issue with the Note 7 is directly a result of the battery since Samsung had two manufacturers make batteries and in both instances Note 7 devices with either battery still failed.

As long as the device is working properly meaning there's no defect that I am aware of (as in no global recall in effect, etc) in any part of the power or charging systems then I tend to leave my devices plugged in until they charge to 100% status then I'll usually leave them connected to the charger for up to 30 minutes past that point then disconnect. With the GS7A I have, I only charge it once every 2.5-3 days typically and that's from 5-10% back to 100% using a Samsung 2A charger - I don't use the factory fast charger and I don't use fast charging because I believe that ends up shortening the potential lifespan of the battery cell itself.
I did not say that's a fact for everyone to live by or accept as the gospel truth, I said for myself personally I believe that fast charging shortens the lifespan of the battery cell itself.
For the record I've owned several hundred devices over the decades, some with Ni-Cad batteries, most with Li-Ion over the past decade, and a few with Li-Po technolology and I only had one instance of a battery having a problem (not a failure). It was a knockoff cheap Chinese clone battery for my Galaxy S4 Active several years ago and it bloated up one afternoon - thankfully that GS4A had a removable back cover and I caught the swelling up very fast because as soon as it started to bloat up the back cover literally popped off about 4 inches above my desk and landed on my keyboard. I of course took the battery out immediately and put it in a small ceramic box my Wife had laying around, nothing else happened and I ended up taking it to a local battery store here in Las Vegas and turning it in for safe destruction.
See, there really is a good reason to have removable batteries and removable back covers on some devices.

As stated above, I don't believe the actual point of failure with the Note 7 is the battery directly - the burning up and explosions of the battery cells is the effect, not the cause. Something is happening to cause the battery (now two different ones, which most of us know about now) to fail.
Now it remains to be seen if the cause can be determined for the failures.
There is one other, perhaps more placebo induced effect, routine I'd do every once in a while, related to battery calibration. So I'd let the battery go as low as can possibly go, or let it turn off by itself, charge at cold until 100% then power on while still plugged in and finally unplug when os fully booted up.
Is this still a proper thing to do or it rather stresses the battery uselessly?
After I got this GS7A I did allow it to run down entirely till it shut off once, just one time and I actually got concerned because when I then plugged in the charger all I got on the display was a battery outline (the white battery icon that's hollowed out) and I was expecting the lightning-bolt symbol to appear there to indicate yes it's charging, after which it should change into the progress meter along the inside bottom of the icon.
That didn't happen.
So I sat there waiting. 5 minutes went by, then about 10 minutes, and I started to worry that perhaps I'd just killed it completely. But about 11 minutes after I plugged in the charger the lightning bolt appeared for about 10 seconds, flashing a few times, then I saw a thin green line across the bottom. Success!
But it did pretty much scare me for a few minutes at the thought of potentially ruining it by doing that so, I don't intend to ever let that happen. Your practice you mentioned of using Tasker to shut down at 5% (not a complete discharge like I did that one time) and to stop charging at 95% is a good idea and something I'm going to have to do more research into.
I've spent a lot of time over the years reading research papers at Battery University and I know that full discharge of a Li-Ion cell is a bad idea but I still ended up doing it. I was actually trying to capture a screenshot at 1% then I planned to initiate a shutdown immediately after that but taking the screenshot just killed it, oops.
But the idea of shutdown at maybe 4% and stopping the charging at 95% (or at least providing me with some kind of alert I can hear clearly and charge or disconnect as required) is a very good idea so thanks for mentioning that.
My research and understanding of the available info at Battery University is that it's better to do your best to not let a Li-Ion cell go below at least 30-40% charged most of the time with short periods of charging to bring it back up to the 90-95% point and, and occasionally - like maybe once a month - allow it to go deeper into the discharge state but not fully (I learned my lesson on that one) and then charge it back to full. The question is what that "full" point might be because some papers say charging Li-Ion to full capacity ruins them as time passes and other papers say it's just fine to do so occasionally - the problem is there's no absolute consensus on either method.
The deep discharge method once a month might work better as a method of calibrating (?!?!) but I honestly don't know for sure, not sure anyone does. But I think I'm going to start using Tasker for that 4-5% shutdown and 95% top off point on my Active, it sure can't actually hurt the device and could give me longer battery lifespan or should I say longevity as you did - that word actually seems more appropriate because most folks hear "battery lifespan" and they only understand that to mean how long it runs on a single charge which isn't the meaning I'm trying to get across.
all i can say after this incident , my knowledge of ion battery deepen and yes in case of emergency , you cant remove if its seal tight shut inside , something to consider , Samsung .
for me, no it's not made me more wary, I always am re Li cells as there have been many failures not only in phones. I have laptops, eCigs, torches etc that all use Li cells. That said, I use the devices as "normal" but stay aware of how warm they've gotten in charge/use, try to not drop them or leave them on/in a source of external heating etc. Anything containing combustible material can go bang after all. A disposable lighter left on an iron fireplace with the fire burning goes bang very well indeed, as would one of these cells in the same circumstances
I tend to top off the charge regularly since I have Qi chargers on my desk and in the car holder but never charge overnight while I sleep. I'd guess my operating capacity ranges from 100% down to maybe 30% and mainly hanging in the 60-80% range as the device tops up. SatNav tends to mean in-car the device only gathers a minor gain even over a couple hours use as the draw from the screen/cpu offsets the input from the Qi charger plate. The phone of course gets warm in this mode, hence it is set halfway down on the centre dash rather than up high and in the sun. And no I'm not always looking at it - voice guidance is very handy
On charge levels, I've also read a number of articles on various cell types. Typically the recommendations are that Li cells effectively eat themselves if kept at 100%, degrading and losing capacity over time. Hence its best if storing them to have them at 50-70% and not fully charged. Of course whether the phone actually takes the cell to its 100% limit or its charge management calls 100% at the 95% of cell capacity I don't know. When fully discharge has happened then yes it does seem to take longer for the charge icon to start ticking along, seen the same on the old iPad-1 I have, probably because the initial part has to be a very slow energising charge to get the cell to a point when it can accept more current and maybe the icon only shows rates above a certain current.
re the swelling cell. I've not used non-Samsung cells in my note 1/3 or S2 but have seen Sammy's cells also swell when they get to end of life. Both notes had this happen around the 18-26 month mark but not to the extent of the back popping off/open. Dramatic shortening of on-battery runtime yes, but from the outside no real visible indications that anything was up.
NO, LiPo, and Li ion batts are everywhere why worry about, I have had dozens of LiPo an LiOn powered devices
What about Li-On batteries though?
Hasn't changed for me either. But it has made me more wary of Samsung devices. There no way I'm getting the s8 (or note 8) no matter how great the features are. They can't even figure out what's wrong with the note 7.. Who's to say their upcoming phones won't have the same problem.
The only thing that worries me is that it may become even harder to get batteries and such shipped to Hawaii, it's horrible.

Hi;
From JerryRigEverything's Teardown video I can tell that is not easy to replace the battery on the G7 plus if would void the water resistance and since I'll keep this phone for at least 2 years I have the following question about how to preserve the battery in the best conditions possible:
In order prevent the battery degradation, is it better to use: Fast or Wireless Charger?
Do you have any other advice regarding this topic?
3000 mAh isn't that great to begin with and if you add that it could get worse over time then it's better to take precautions. I wouldn't care that much if replacing the battery wasn't that hard. I mean it would require a good technician in order to get a proper reparation and I'm not sure I know one.
I apologize for the spelling or grammar mistakes, I'm not a native speaker and I'm still learning.
Charge whenever you can and dont let it go under 50%
The more you discharge it the chorter lifespan it get
Disable all crap you do not use.. When at home, and phone not used much. Turn off Wifi, BT, Location and even Data..

According to what I've read. I think the ideal scenario would be mantaining the battery charge between 20% and 80%.

Yes. That's exactly what I do with every smartphone I've own. I usually go heave on optimization of every single aspect regarding performance and battery life.
I use WIFI on, Data off, BT off, location off, auto brightness setting, Always on display off, no facial unlock, WhatsApp tweak to get only important notifications, the display is set down to 1080p instead of 1440p. When I play PUBG mobile I turn on Airplain mode and plug in headphones.
I purchased Acubattery. It has alarms that let you know if you are overcharged (more than 80% it says).
It also does a really good job of monitoring your current capacity and giving your hints on what is draining your device during the day. It will estimate your current battery capacity, which is nice if your phone shows they battery condition as Good (whatever that means Huawei Nexus p6).
Basically your battery is going to self destruct, but I find this app really gives you a good amount of information to make good decisions about how you use your phone.
I disagree with every advice here!
Check out my thread from my last phone :
https://forum.xda-developers.com/xz...ry-restore-t3796461/post76653346#post76653346
Been reading dozen of threads on diffrent forums regarding people complaining about their poor battery health, performance, etc.
Here are my advices to obtain near 100% battery health as years passes by (I have an galaxy s3 from 2012 with 90% and an LG g3 dual sim from 2014 with 92% ???), it all has to do with user behavior:
1. Avoid not charging to at least 95% then discharging it to near 0% (example: you charge it from 0 to 50 then you go outside and discharge it to near 0)
2. Avoid high usage for more than 3 consecutive days.
3. Drain SLOWLY from 100 to 0 once a week. This drain must be done at least in 1,5 - 2 days.
4. Charge from 0 to 100 with phone off at least 1 time / week
5. Every 2 weeks Let the phone discharge in 2-3 days, with minimal use, like just calling.
6. Repeat nr. 3 as much as you can
7. Avoid putting to charge when the phone is hot.
8. Avoid charging while using the phone.
9. Avoid fast charging.
10. From 100 to 70 and from 30 to 10 go slowly.
11. Never let it discharged 5, 10, 20 % more than 1 day
12. Never charge from 20, 30 to 100.
And many more will come.
Cheers.

There are so many things that could affect your battery life over a 2yr period. I own both the G6 and G7 and the G6 still gives me pretty good standby and SOT after 2yrs.
General rule says you avoid fast charging wherever possible as this will affect battery over the long run. Avoid scenarios wherein the battery might overheat.
Also little things like simply living in an area with bad coverage will eat through your battery like nothing else.
If your worried about battery replacement, im fairly sure LG service centres do it for a pretty resonable price anyways.
