Qns related to buying new HD2 battery?

How often do you change your HD2 battery? when do you know you need to change it? sorry if this sounded silly!

Well, Ive had mine since november 09 and never changed it. Still holds a decent charge, probably not quite as much as when it was brand new but cetainly not a noticeable difference.

when to change batts.
Typically a li-ion battery will lose 20% of its capability after one year (even if you don't use it) A few things can influence the exact amount (keeping it always at 100% will speed up the loss, as will high temperatures)
If you really want to know exactly what the loss is.....
Fully charge a battery and remove it. Leave it a few hours or overnight and then use a voltmeter to see what the voltage is. This will tell you how much capacity it has lost.
4.18v -4.2v=100% (ie perfect battery)
4.10v = 87%
4.0v =75%

I have a an old magician I bought new 8 years ago & still works with original battery.
My touch pro is almost 3 years old & still works fine lasting 2 days on energy ROM with original battery & the same can be said for wifes old Diamond 2 Topaz.
Doing output test & using HTC battery test exe may help determine battery condition if battery is suspected faulty.
My conclusion is a genuine good battery should see over 2 to 3 years use without noticeable performance loss & have a serviceable life beyond 5yrs.
Modern devices such as HD2 which has a small battery & drains a lot of power so may lower the battery lifespan as you will be charging that tiny battery almost twice as often, also current battery material quality may have declined.

Do you think that a non-removable battery will be a problem?

I currently have a Samsung Galaxy S5, and I'm seriously thinking about upgrading to the S7 Edge...however the fact that I can't change my battery is one of the problems I'm afraid of. I'm a hardcore gamer, and after 2 years, my battery for the S5 was dying quickly, so I had to change it. I started using the phone almost all day to play Marvel Future Fight towards the past 6 months and that is what really messed up my battery I think. So I'm wondering if I upgrade...if the phone will last 2 or so years? Cause I ain't got the money to be upgrading every 6 months or every year lol.
What are your thoughts?

Even tho it doesn't has a removable battery like your s5, you can still have the battery replaced by Samsung. Downside is that you can't carry an extra battery with you in case you run out of battery during the day.

So I came from the LG V10 with free extra battery promo. I went through 2-3 full charges a day. I've been on this battery since 8am today. It's 5:49pm and I'm at 54%!
Oops sorry... Just realized you're more worried about the battery's ability to hold charge down the road.
Haven't owned a phone more than 6 months so I'm not sure lol. You could always get one of the charging cases later on when prices drop.

Lol yeah the battery lasting long sounds amazing, but after 6 months of gaming every day, I'm sure it will take a toll The charging cases sound like a pretty good idea though.

It does costs more than getting an extra battery for your s5, but you won't have to pay for a new phone every 1-2 years. Nowadays most phones have non-removable batteries, except for the Lg G5, but it has a 2800 mAh battery when the s7 edge has a 3600 mAh.

it's not an issue in the sense that no one keeps a phone 4 years nowadays. For instance, using a QC 2.0 adaptor shortens the battery life, however over 1 or 2 years, it is barely noticeable. It is noticeable only if you keep your phone for years and years. But most people change every year.
These batteries are good, they're not super cheap, so it will be ok. Samsung replaces the battery only if it's really defective, not if you lost like 5-10% of the battery charge.

I have two bloated S5 batteries first lasted 18 months and second lasted 6 months which was last week. I was a very heavy user and my phones over heat. My old HTC EVO had to be in the freezer a lot and had 5-6 batteries. But I believe a with normal use the battery should last 24 months. I have been thinking of putting phone on discharge timer to plug in and unplug.

I've never had an issue with my S6 Edge that I'm trading in for the S7 Edge.

True that, but would they just replace your battery or the whole phone itself? Like would I have to back up my data?

That's very true, and I had no idea that QC 2.0 shortens battery life, does QC 3.0 do that? I know we'll be getting that with the wireless charging. Regarding replacing the battery, what do you mean by "really defective"? What do they consider defective? I find that loosing 5-10% battery charge in less than an hour really defective lol.

Damn, well I'm barley on my second battery after almost 2 years lol. My S5 overheats a lot now and sometimes I don't use it much. It lags a lot and sometimes messages don't send..so I really need a new phone. :/ How do you put the phone on a "discharge timer"? I'm thinking of not leaving my phone overnight charging cause that's how the battery messes up more I heard. I probably also won't play games while charging my phone either cause that'll kill the battery's longevity more than usual.

They will replace just the battery, for the s7/s7 edge they use heat to open the back cover and they replace the battery. On the s6 they also had to remove the screen in order to get access to the battery (you can watch videos of how they do it).
From a quick search online, it costs $45 + shipping to replace the battery on the s6 in the US, I could be wrong as I have no personal experience.

I know we're talking about different device's but my z ultra (heavily used) and Z3CT both still rock battery like the day I bought them. Hence why I'm not worried to much. Don't let it put you off a device also you could always change battery after a while just a little bit harder to do lol.

My previous phone was the S5 and I wasn't to happy about going to a phone that doesn't have a removable battery seeing as all my phones had a removable battery. That is one reason why I went with the S7 Edge so I wouldn't have to worry about the battery as much.
With my S5 and before that my S3 I would just keep the phone plugged up if I was playing a game that used a lot of battery.
Get the S7 you'll like it.

Nice, I just hope the S7 is the same way lol. Sure, we can always change the battery after awhile and it'll be harder to do, but it'll be more expensive than just buying a battery outright like someone said earlier in this post But...it'll be worth it lol.

Yeah, that's exactly how I feel lol. I've been doing that with the S5 and before that the S3 and I really do feel like it kills the battery's life more while leaving it plugged in while playing a game. :/ But I already pre-ordered the phone today from T-Mobile so I should have it in 3 days or less

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.

Nexus 6P Replaced battery health

Hi all,
Recently I have exchanged a battery at a local service provider, battery they showed before installation seemed as legit as they come and after replacement phone felt way more agile especially at a lower battery charge levels. So I was happy until I started investigating poor SoT that I thought at the time was due to the Oreo update. After some time, resets and reinstalls it feels like the system is as healthy as it can be for now, but Accubattery shows 83% health at 2,853 mAh out of designed 3,450 mAh. That is only after few charge cycles, but I am still worried that it might a permanent battery hardware issue. Right now at latest Oreo build with elementalx kernel running a wingoku gov profile I get around 3 to 3,5 hours of SoT with little use, over night after 100% charge phone looses around 10% percent by the time I wake up.
If anyone has any insight into similar issues and can confirm Accubattery health stats credibility I would really appreciate.

Sorry, but you got a bad replacement battery. It happens. Although it just provides an estimated value, I've found Accubattery to be a very solid indicator on the phones I've used it on. Since your battery is barely above 80% it takes the guesswork out of the equation. The battery capacity estimate converges quickly to a value after only about 3-4 charges. That's it. It's not something else with the phone. It is the battery itself. There are literally dozens of threads discussing which batteries are good replacements and from which sources. Buy one of those and your problem will be solved. There are some Accubattery haters out there, but I guarantee based on what you are saying, your battery is a dud. With a fresh, high quality battery you should be seeing very high 90's to low 100's. Yes higher than 100% because some batteries sold actually have a higher capacity than rated. Try to get one of those.

Thank you for a reply.
At this point I guess I will just have to live with it until I buy a new phone, I only decided to give this one another go since I love it and do not see anything on the market now that would appeal to me as much as 6P did at purchase. But I do not want to spend more money and time on this, just wanted to make sure this is not a software issue. Software I can tweak, but battery replacement yet again is too much.

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
