Everybody's hoping it at least has 2GB of RAM this time around though. If you can afford to buy a new phone - I say do it. Not sure what to tell you on fixing that :\ This phone seems to get as hot as my old Galaxy S3 or my girlfriend's Moto X. The only instances where I experience freezing\lag is when activating the Dual Window pane.Īs for heat issues. I can't say I've dealt with freezing on my LG G3. >Issues: - freeze on chrome - freeze on Maps - freeze out if nowhere - painfuly hot Take GSam for a spin to maybe determine if this is the source of your poor battery life (and consider getting a fresh battery). If apps aren't the problem, then another area to be looked at is battery health. If you hardly used the phone and the screen was off for nearly the entirety of the 3 hours then I would start looking at whether you have any abusive apps. It seems like people average 3-4h SOT with the LG G3. If you were using your phone continuously (Screen ON with high brightness ON), then these stats aren't unheard of. >I use my phone to work and this phone just isn't reliable. You should have discovered more quickly whether or not the device was botched. So you bought the phone in February, this was 7 months ago. >I'm starting to think that I got a broken product. New, advanced battery chemistries such as lithium-sulphur and lithium-silicon are also being worked on, with companies around the UK currently developing the technology.I like how the two alternative phones you list are polar opposites in terms of price-range. “For higher power output, you need a more porous structure to increase the surface area and allow more lithium ions through at any one time, but because it’s got more holes it holds less active material, which in turn gives you lower capacity.” “If you imagine inside your battery you have this porous structure full of the active material.” “It’s about optimising the structure within the battery,” says Wu. In the immediate term, battery advances will come by bringing existing lithium-ion technologies closer to their theoretical limits, which will increase the power density of batteries.Ī typical lithium-ion battery using lithium manganese oxide has a theoretical power density of 280 Wh/kg, but the final product only has 150Wh/kg so there is certainly room for improvement. We’re stuck with the rechargeable lithium-ion battery for the time being. The only way to immediately increase a smartphone’s battery life with current technology is to increase the power efficiency of the smartphone’s electronics and increase the size of the battery – but thinner and thinner smartphones demand thinner and thinner batteries. While Lithium ion battery energy density has improved since its introduction in the early 1990s, it is held back by its construction and chemistry. Everything that is not the active material within the battery is effectively dead weight, including the casing, the controller chips, the wires to carry the current out – they all add weight but not power.Ī typical lithium ion battery within a smartphone has an energy density around 150 Watt-hours per kilogram (Wh/kg). The major limiting factor for batteries is their energy density.Ī battery can only generate as much electricity as its chemical components can store energy. The principle of the battery may be simple, but the chemistry and technology to make it work is not. Low battery symbol on the Nokia Lumia 800 in a jeans pocket. Positively charged lithium ions travel through the electrolyte from the anode to the cathode driving electrons through the smartphone as required and back to the anode. Lithium-ion batteries found in most smartphones and electronics have a metal oxide cathode made of a cobalt, nickel, manganese or iron mix, a porous graphite anode that holds lithium ions within it and a lithium salt electrolyte. Inside a typical battery you have an anode, a cathode and electrolyte – something for the positive ions to travel through. Once charged, the battery can then create electricity by driving electrons through a circuit, in this case a smartphone, to the anode and will continue to do so until all of the electrons contained within the battery have transferred to the anode or a built-in switch disconnects the battery. When a smartphone is plugged into the mains, electricity is used to reset a chemical reaction within the battery, transferring electrons from the negative anode to the cathode – the positive end of the battery.
