hey
i readed that li-po battery is better then normal battery
maybe there a battery that could fit to rezound and work with it ?

maybe this could be modded and fit to rezound ?
It's a complicated issue and there's not a clear cut "better" technology. They're both better for different applications. In practice, Li-Po hasn't proven itself to be any better for mobile phone applications than Li-Ion. It's theoretically safer due to the higher resilience to overcharging, and it's able to be made thinner due to the dry electrolyte, but the overall energy density is lower, so you'd get less power out of the same battery size, and they don't last as long as a standard wet electrolyte Li-Ion.

Lithium-ion-polymer has not caught on as quickly as some analysts had expected. Its superiority to other systems and low manufacturing costs has not been realized. No improvements in capacity gains are achieved - in fact, the capacity is slightly less than that of the standard lithium-ion battery. Lithium-ion-polymer finds its market niche in wafer-thin geometries, such as batteries for credit cards and other such applications.

I can definitely see why lithium ion is in use more than LiPo, after having learned a lot about LiPo battery technology and high performance electric motors and things like that. With the cheap manufacturing process and corner cutting that goes on with such a scale of mass production like main stream smart phones, planes would be falling out of the sky due to all the smartphones that would be exploding.
I use to argue the other way, that as long as people used them responsibly and didn't jack around with voltage changes and used OEM chargers it wasn't dangerous. Then I started paying attention online to how many people will plug their phone up to any charger they find buried in the back of their family's chicken coup dumping grounds.
Lipo batteries are MORE dangerous and susceptible to overcharging than Li-Ion. Lipo batteries expand when at a high state of charge, and overcharging causes rapid degradation of the cell, to the point where it short circuits itself and explodes in flames. That's why those of us in the RC community use fire socks to contain charging Li-Pos...

My old droid X came with a LiPo batterry...after just 4 months of use it started to expand and get very hot...luckily i heard about this issue and bought a li-ion and the phone still works the last i knew...i gave it to a buddy like a month or two ago.
i think Rezound take more power then its tell in idle mode
for example if the phone idle for 10 hours and u got 50% left its will drain faster
then using it for 1 hour and then get 50%
also using the phone while recharging make the battery percent not correct
slow recharging can help battery recharge more energy

Those are wakelock issues that are easily fixable...have you looked into this and disabled them....alot of people have had alot less battery drain after doing so...i suggest viewing whats juicing down your phone to ensure that is what it is...a few of the 4.3 threads have explained the issue....LiPo batteries i hate to say it are made cheap and you get what you pay for...i'm speaking from pure experience
I've been looking at the extended batteries from powerbear and the like. None of them list which battery cells they use in their batteries. I've also seen a lot of complaints of the batteries dying at the 3 to 6 month mark.
Does anyone know which batteries use high quality battery cells, for example Samsung cells or at least the OEM battery cells?
Does anyone have long term experience with one of these batteries that hasn't degraded significantly or similarly to the OEM battery as far as equivalent capacity loss over time?
I posted this question on Amazon for a number of the extended batteries and only received a response from the
PERFINE who claim to use LG OEM battery cells.
No luck with responses from Powerbear, Zero Lemon and others.

No idea, i can say ive been using powerbear for 5+months now with no issues. Battery life has not degraded more than 5-15%. Most likely the cells are lower quality, but the larger capacity should allow you to often have a lower depth of discharge and help them to last a bit longer.

Thanks for the input, I'd really be interested to see how the battery holds up after the 6 mons. mark. Also, I'm assuming you're a heavy user.
Another thing I recently read was the way some of these batteries are put together. Some are simply two regular capacity batteries put together. Apparently this is a bad idea because the leveling of the battery usage isn't controlled since they are technically two separate batteries. Anyhow, it's good to hear the powerbear is holding up pretty well.

Third party chinese batteries are always a bit hit and miss. I have always used them like if it doesn't catch fire it is good. Putting two cells in parallel is not as bad as putting them in series so I would not worry about the balancing. They are poor quality batteries anyways so balancing does not give that much advantage in this scenario.
If the battery costs something like 20 bucks then don't worry about it lasting more than six months. It's cheap so just buy a new one if you want the best battery life. But don't get the cheapest if you don't want Note 7 problems. They have really poor quality cells and most likely no protection. Death traps if you ask me. 20 bucks should give you the protection and not the worst cells.
Maybe there's something, like a chip, that detects battery degradation. And when it reaches a certain point, a sustained battery incorrectedness(word?)sets it off into the infamous ir-repairable Boot Loop of Death....i wish i could add a sound effect of that last sentence echoing to signify the fear and importance to avoid this "unknown why" issue. This bugs me that there isn't an answer for it(at least that i know of) and Google seems to replace them as if it was something they expected to happen???
Anyone else have any thoughts on this, please SHARE.
I'm worried about my lifeline to the world dying on me and if there's something i can do to prevent this from happening, by all means please tell me!

There are two distinct issues being reported by some users of the 6P. One is the manufacturing quality of the motherboard and the solder used (motherboard failure), and the other is a very poor quality battery prone to early degradation (battery failure). There is nothing at all you can do about the first issue. Luck of the draw. On the second, you can proactively monitor the battery capacity compared with the original capacity (3450 mAh) using an app called Accubattery. If your battery does start to degrade, you install a quality replacement. The battery issue seems to be much more prevalent. On the positive side, an overwhelming majority of users have not experienced either issue. Nothing to be done other than keep an eye on the battery and intervene early if required.

I have and have used accubattery for awhile now, and my actual battery percentage, is about 83% unfortunately. Is changing the battery a very complicated thing? That you know of?

Replacement time. Sucks but it's true. The Cameron Sino seems to be the most popular among 6P users. I don't think it is too difficult, and there are a growing number of YouTube videos. Seems like you need a heat gun or good blow dryer to soften the glue and the usual plastic tools. Or... you could always order the battery online and take it to a repair shop.

Thanks for the link. Strange enough, i just clean flashed the rom i usually use, (it was updated for the security patches) anyways, i charged my phone to 100%, i usually never do, I only usually charge to 86% based on "Accubatterie's" insistence that it is less wear on your battery. And at 100% charge, my battery health is at 86%. Coincidence? It is also a fresh app install of Accubattery, i have the pro version and the health is only based on the one charge...

You should not give much focus to Accubattery % there is not real way of knowing the battery degradation specialty because Android itself is not collecting most of the data.
How old is your phone? If is over a year is totally normal to start noticing the difference in battery life. Best choice is to just replace it.

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:

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?
The lie of requiring a non replaceable battery for water proofing is also an issue. Forced obsolescence sucks....

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."

PC mag S8 review
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!
Fellow Note 8 users, I recently got to replace my 1.5 yr old battery with a new bigger capacity one. 3500mah from Polarcell... Once I get a few charge cycles going with this one I'll post results!
I had 255 charge cycles on the old one and fg_asoc was 92, fullcapnom 2890.
Evidently as I'm a very curious person, I had to test the capacity of the old battery with a high tech hobby charger/discharger from Junsi, the 4010 DUO. As it stands out, fully charging the battery to 4.4V and then doing a deep discharge to 3V netted me 3273mAh. Be aware that this is a way deeper charge/discharge cycle than the phone would ever do. In order to prolong lifespan, Samsung is not using the full capacity of the battery.
Whether there's an algorithm tied to battery aging and fg_asoc, or the battery is actually a bit higher capacity than spec, it remains to be seen. I'll conduct more tests, and keep everybody posted.
Ask away any question the you may have and don't be bummed out it your Galaxy battery is reporting lower capacity from the start. It may not be the case.
Cheers,
Andrei.

I've notice DJI doing the same thing with my Phantom 3 drone batteries whenever I use a hobby-grade charger connected directly to the terminals of the battery itself. I say this is a good design by Samsung if it is as you are suggesting.
Good thinking, I have a ph3 battery lying around wi5h no more than 50 cycles on it. I could measure that too!
You need to remember that your Phantom 3 batteries have a nominal 4.35V per cell as opposed to the usual 4.2, so you would need to factor this in to your hobby grade charger. I have a Hyperion EOS.... model. I've used this to "revive" several phone and laptop cells in the past (once the cell isn't internally damaged).
I don't think one needs to be concerned about fg_asoc or fg_fullcapnom once there isn't too much deep discharging of the cells.
Yes, I'm aware of that. Sometimes I undercharge my ph3 batteries by 0.05v to make them last longer. The 4010 duo is one hell of a charger and I love it!
Back to the note 8 battery, I'm getting spectacular battery life with the new bigger cell and the One UI update. Currently at 60% remaining with 24h of use and 3h of SOT. Stellar!
Cheers!
Just a question, did they reseal the back cover for waterproofing after?
There's no they, I did it myself. Bought some original Tesa double sided tape from ifixit.com and it worked great.
