I red last week somewhere that a liion battery lifetime isabout 300 times charging, does anybody now or this is true?

You can find there answer to your question..
The life span is dependent upon aging (shelf life). From time of manufacturing, regardless of whether it was charged or the number of charge/discharge cycles, the battery will decline slowly and predictably in capacity. This means an older battery will not last as long as a new battery due solely to its age, unlike other batteries. This drawback is not widely published.

i must charge my diamond 2 or 3 times a day duz that mean im gunna have to buy 3 batterys a year lol

same, my diamond is connected about the same amount of times per day, and then left on charge when im at home to ensure i have adequate battery, eek!
I think the 300 times charging is refer to 300 full complete cycle of charging. It need to be refer to complete a cycle from fully discharge to fully charge. If you charge your battery from 50% to 100%. It is only 1/2 cylce.
Anyone can correct if i'm wrong.
I think a complete discharge counts as 1. If you charge the battery now and then without letting it discharge completely it will last longer. This is quite Li-Ion specific.
In heavy usage a battery lasts for 2 years easy.

Even when you charge it 2 times a day? This should mean about 1400 charging?

Right, firstly, forget anything that has been written above. 300 is crap. (the film '300' isnt tho)
lithium ion batteries generally last longer when kept topped up, rather than cycled.
The batteries in out Diamonds are lith ion, but have been specifically designed for top up charging, therefore last longer.
you can expect your battery to last for 3 years of continuos use, unless there is a fault or it is damaged. It will slowely deteriorate over time.
I have just bought a new battery for my laptop, which is Lithium Ion, as was the original. This is after 10 years!

OK. I know it is out of the topic, but i still want to say: My laptop which is a precision workstation laptop's battery only last 1 year.
So, it is fair that if you discharge and charge frequently, it will deteriorate faster. This is fair enough.
Li-ion battery life - the facts
Skipping back to the facts for a moment.... the HTC Diamond standard battery is a Li ion battery with Co chemistry.
1. Li-ion batteries last between 300-500 deep cycles (from 0% to 100%).
2. Partial recharges are good. A partial recharge from ~25% to ~75% is less damaging than a recharge from 0-100%, and only counts (roughly) as around 1/4 of the impact of a deep cycle. Li ion technology has no charge memory effect, which means that the battery capacity is completely unaffected by partial charging (n.b. this is NOT the case for NiCad or NiMH technology).
3. Li-ion batteries also decay at a constant rate over time, dependent on temperature, and regardless of use. They lose around 20% capacity per year at 25C, but this is increased at higher temperatures. Shelf life is optimised by keeping unused batteries at 6C (fridge temp) and with ~40% charge. But do not freeze them!
4. 100% charge causes accelerated decay rates. So keep your battery below full charge.
5. Deep cycle the battery occasionally (~once per 30 charges), to recalibrate your charge meter. Otherwise the charge level shown will become inaccurate.
6. Key advantage for Co chemistry is high energy density - up to 200mWh/g. Key disadvantage is the charge/discharge limit, which is ~1.2 coulomb.
7. Conclusion is that you can expect your Diamond battery to last for ~3 yrs of hard daily use. If you take care of it, it will last for double that time.

Just bought a 3500 mAh battery off of ebay. I was wondering do i need to condition this battery? If so what are the steps? I see conflicting info all over the place.
thanks!
Conditioning? Like calibrating?
Some batteries said to drain it completely first then charge for 8 full hours to condition it. That's why i was wondering if there was anything i needed to do to get the maximum amount of battery life out of it.
That's a great question. Usually I let it drain fully, then fully recharge. It's just an old habit of mine with new batteries.
usually when you get a new battery itll have some charge in it you need to power the device on let it drain completely till it wont turn on at all then let the battery charge 8-10hrs and you should be good.
Hi everybody,
I had a problem with my original battery. It dried every day in about 10h of usage. It was horrible, so I bought 3500 mAh battery from ebay and it was OK. I didn't had to charge my battery for about 2 days. Really impressed if I compare this battery and original, but problem was, battery from 3500 mAh was really big and made my phone look ugly, so I bought new battery. I've bough new Onyx battery with 1400 mAh and battery drains in less than 10h. I used my phone for about 2-3h and battery was on 4%. I haven't played games or downloading anything. Just chating. Does anyone know what's wrong? Is that normal for onyx battery or can I do something to improve battery life?

you can buy an original battery for your optimus 2x =)
Does fast charging Daily overnight reduce long term battery health? Is it a better choice to only fast charge when necessary and normal charge overnight?
I've reading about this lately but never came across a definite answer. I was hoping that someone could answer this for me.

Depends on quality of the battery and the capacity of the charger.
In general batteries are charged with 10% of the capacity. For the Nexus 6 battery with a capacity of 3200ma/H, you need a charger with a capacity of 320ma. Assume you need 10 hours to fully charge the N6 with a charger capacity of 320ma.
In theory the N6 charger with his capacity of 1600ma will charge 5x faster.
But the the N6 charger is not permanently in this turbo mode. After some time it switches back to a lower capacity when the battery is partially charged.
Now your question. In turbo mode charger and battery dissipates heath and that is not good for the battery. So normal charge will be better.
But there is also battery drain when you use the N6, especially the nice amoled display.
Battery drain causes also warming up of the battery.
So the total battery life depends not only on (turbo) charging. Also the way the N6 is used.
Hello,
i've recently purchased a new Samsung Galaxy Tab S2. It looks like the tablet had been lying in stock for quite some time, as it only had 28% battery left when i powered it up. The first readings from the monitoring app i use (AccuBattery) estimated an effective capacity of around 5600 mAh out of the 5870 mAh design capacity (95% health). After one full charge cycle, i've been doing small cycles as is advised pretty much everywhere when dealing with Li-Ion batteries, never dropping below 20% and never going above 70%. A 50% charge cycle, from 20% to 70%, is worth 10% of a full cycle, according to the app.
Now here's the catch, in just 2 weeks of use, and what must have been 3 cycles' worth of charging tops, the battery health already dropped from 95% to 92%, and is now resting at 5421 mAh estimated capacity. The amount of mAh gained from a 50% charge also reflects this. It's also worth noting that the built in battery indicator shows the same percentages as the app, which would lead me to believe the readings are accurate, or at least that both are either right or wrong.
I find it highly unlikely a barely used battery could lose 3% of its capacity over the span of 2 weeks, so what gives? Could it be the infamous "memory effect" at work, even though Li-Ion batteries are supposed to not be affected by it? Or is the battery bad?
I'd like to shed some light on this topic, as there's a lot of contrasting opinions about it.
