#6. Be careful of what hacks you about online.
Some sites are saying to download Google Maps and work within offline settings to save battery life but Sam Thorogood of Google has advised against this. Instead, look to #7 for a real solution.
#7. Invest in a portable mobile phone charger.
An Online Shopping retailer reported that their sales have increased a whopping 243.51% since the launch of Pokémon GO. This game eats your battery, so it’s best to be prepared.
#8. Be strategic about using your Lucky Eggs.
Make sure to use your Lucky Eggs when you evolve a bunch of your Pokémon or when you hatch a good number of your eggs. Popping the egg will get you double XP for half an hour, so you can level up pretty quickly with this method.
#9. Another piece of advice when leveling up quickly.
Make sure to save Pidgeys, Rattatas, Weedles, Caterpies, etc. or any other Pokémon that costs 12 or 25 to evolve.
#10. Avoid evolving Pidgeottos into Pidgeots unless you need them for a battle.
This is a special note from Kilroch, also included in his advice about leveling up.
