Finally, also imported a Razer Blade 14 and now i'm trying to maximize its longevity. On the one hand, this concerns heat and the dust it will collect, but i just started optimizing this. Currently, I'm more interested in optimizing the battery lifetime. I tried to install the Lenovo Energy Managment Tool (which includes a charging threshold), but that did not work out (as expected). Sony is also offering such a tool (for its Vaio line), but i assume this will also not work as these tools are usually tailored to specific battery firmwares.
Hence the questions are boiling down to:
- Is there a generic battery charging threshold utility ? (..probably not..)
- To my knowledge, it is best to always discharge the battery to around ~10% before charging ? (Because keeping the power plug in all the time will reduce the amount of charge cycles faster but deep discharge is also not advised for Li-Ion batteries?)
- Is there anything else i can do ?
-

Deep discharging is bad for the battery. Best bet is to leave it plugged in, reduces charging cycles. If you can't set up a 60-80% constant charge scenario it's best to just leave it plugged in or charge it as soon as possible. Letting it constantly discharge will reduce life.

look at thing on another way, the battery is rated certain number of full charge cycles, which translates to a set amount of time to be used, this means we can translate full charge cycles into amount of time the battery can run before dying, given that when the laptop is plugged in it will not discharge the battery, and will cut of supply to the battery when it is charged to a certain level, this means the battery longevity is directly related to its time being unplugged
straight forward explaination isn't it, its like you setup a circuit where the battery gets charged and discharged at the same time, when it dies after a long period of time it stops getting charged nor discharged -> the only way to extend its life is when the circuit skips the battery which is when you see on your battery icon saying (plugged in, not charging), it means the battery is there but it isn't part of the circuit, same as removing it but safer in case of a power surge -
And as well if you leave your notebook plugged in most of the time and you have a "battery saver" option that will limit it to 60-80% do that. "Storage" (which is essentially what is happening if you are always plugged in) at full charge is also detrimental.

^As far as I know there is no way to do that on the blade 14. Is there a setting in windows to keep it between a certain range?

Don't worry too much

Don`t leave it plugged in!, trickle charging destroys the battery since it technically constantly charges and discharges keeping the battery toppped up aroun 98-100%, try not drain the battery below 15-20%. The optimal levels for lithium batteries are around 40-75% according to toyota. You can also set your max processor state to 99% in power manager, this will disable turbo boost and give you about 50% more batterylife, assuming you get around 4 hours on high performance, you will get about 5.5-6 on power save with this setting, if you have longer batterylife you will need to charge less often and as a result will prolong the life of the cells.

Of course it's not going to be exactly the same as just removing the battery since it is hooked up to circuitry, but it's close enough if we're talking 10 days to go down 5%. -
So how do you limit it to 80%? I would like to know please

- This is called a charging threshold - offered by tools like Lenovo Energy Manager or the VAIO Tools. Meaning its probably not possible at all to do this on the Razer. To my knowledge (and experience), trickle charging is really bad. Nearly all laptop batteries are dying within 1-2 years because of this. .. but I'm not totally convinced always discharging is the better way. .. Hence this thread
-
Sammy gamer 7 has the option in the bios (also exposed in their software)..
Not sure if there is a general tool for it.. -
If the battery is expanding send it for service ASAP.. It's a safety concern..

Wrong thread? Hope that guy figures out whats wrong with his 2nd gen blade. That bulging is concerning.
